Witnessed at first hand how boxer embraced his lifestyle of Bentleys, private jets and shopping sprees - all of it paid for in cash

The cash-rich and often bizarre world of boxer Floyd 'Money' Mayweather Jr. is today exposed by his former executive assistant.

Tasha Robinson-White worked for Mayweather, 37, for 12 years operating within his inner circle as the boxer's 'right hand' woman - and has now written a tell-all book about her extraordinary career.

In an exclusive interview with Daily Mail Online she reveals how she witnessed 'Pretty Boy' Floyd's extraordinary rise from a cocky young sportsman to undefeated boxing champion of the world in five different weight classes.

In a sensational account of the sportsman's personal life Tasha, 42, reveals how Mayweather became deeply consumed by the trappings of wealth; lost $15 million after being duped by a conman; surrounded himself with an entourage of paid strippers and hangers on; and gave cash and presents to strangers.

Tasha, whose book Right Hand To The Champ is published this week, was by Mayweather's side almost every day, fitting in around his unusual routine.

When the fighter was not in training he would sleep from 6am until 3pm each day before spending two hours dressing and grooming himself.

He selected what designer outfit to wear from his vast walk-in wardrobe, which included a separate room for his furs and a room for his leathers.

Then at 4.55pm he and Tasha would drive in separate cars to see his personal banker at a Bank of America branch near his Las Vegas home where he would withdraw, on average, a staggering $100,000 in cash.

'He didn't like credit cards,' explains Tasha. 'So he always wanted large amounts of cash with him at all times.

'He kept it in a large duffel bag which his staff called the 'pregnant duffel' because it was always bulging with money.'

Two burly security guards follow Mayweather wherever he goes to keep him and the cash safe.

Tasha said the boxer lived and breathed money and became more and more 'flashy and flamboyant'.

He even made his friends sit in the back of his car so he could ride with the duffel bag up front.

Tasha says he blew his money during extravagant shopping sprees, on expensive fine dining and lavish nights out.

He also liked to splash out on new cars, collecting luxury vehicles like 'toy cars'.

'I remember him buying six or seven cars in one day,' recalls Tasha.

'When he bought me my Mercedes the dealer told me that that was the 33rd Mercedes Benz Floyd had bought from them.'

'Money' Mayweather – who can earn $15,000 a second during some of his big pay-per view fights and is said to be worth $85million - once tossed $100,000 in cash around like it was confetti at a strip club.

In 2008 he hired out a recently closed strip club in Las Vegas to host a wild 'strip-off' contest to impress his close friend, hip hop artist T.I.

He arranged for dozens of professional strippers to be flown in from around America to compete in the event as part of one of his infamous 'Mayweather weekends'.

The girls were battling to win a $100,000 cash prize but as the night wore on an excited Mayweather decided everyone should come out a winner.

Tasha, who watched on in astonishment, recalls: 'He went up on to the balcony and tossed wads of cash out on to the floor below, $10-$20,000 a time, there were strippers on their hands and knees picking $100 bills, it was crazy.'

Later Mayweather hosted an after-party at his Vegas mansion and during the wild night the boxer threw more cash into his swimming pool.

He and his pals laughed as several strippers dived in to the retrieve the cash from the bottom.

Tasha said Mayweather's favorite hobby was shopping, regularly visiting high-end department stores in Vegas, splurging on designer clothes and jewelry.

He would spend more than $35,000 on clothes and shoes at a time, sometimes every day.

But she says his generosity bordered on the ridiculous when he also insisted on buying all his staff clothes as well, including the bodyguards.

She said: 'Floyd would buy $1,000 jackets, $300 jeans, dozens of shirts but then he'd buy stuff for everyone with him, which ever girls he was with, me, the body-guards.

'He'd even stop strangers in the store and buy them clothes or take care of their tab at the counter, it was crazy spending.'

Most of the time ladies' man Mayweather would insist on travelling with a minimum of a three girls by his side.

The women, mostly strippers he had met at strip clubs, were paid to accompany him on his private jet or in one of his Bentleys.

And Tasha says she would see one girl or another leaving his house most days.

When the boxer traveled back to his hometown of Grand Rapids, Michigan, he'd insist on paying for all of his entourage to fly first class.

When he arrived at his destination city he had a network of strippers on hand to meet him at the airport.

But Mayweather was never interested in getting lap dances.

'One minute he'd call a stripper over at a strip club and she'd be butt naked, the next she's sat next to him fully clothed and they're hanging with us,' said Tasha.

'He'd tell them to tell their boss they're taking a leave of absence.'

Mayweather's generosity did get Tasha in trouble with her husband Kevin, however.

Her boss would buy her extravagant gifts, jewelry, designer clothes and once a white gold Cartier watch.

But the star crossed the line when he offered to have his personal jeweler clean Tasha's wedding ring.

She said: 'When it was returned I discovered Floyd had paid for a $10,000 diamond to be installed in the ring.

'As you can imagine my husband Kevin wasn't impressed at all.'

Despite his generosity Mayweather's staff would often go months without being paid their salary.

He always wanted large amounts of cash with him at all times. He kept it in a large duffel bag which his staff called the 'pregnant duffel' because it was always bulging with money.

'He would say things like, 'well I bought them a Rolex didn't I,' explained Tasha.

'Getting paid by Floyd was completely unpredictable, if the wind was blowing south, if he was in a good mood, then he may decide to pay you, or you'd just have to wait.

'But he was so generous other times that you put up with it.'

To frustrate his staff further, Mayweather often placed large bets of $40,000 plus on football or basketball games.

Tasha says Mayweather was obsessed with his closet and would instruct staff to clear it out every 60 days, throwing away clothes that he deemed 'not in fashion' any more.

She says most things he only ever wore once before they were discarded.

On one occasion she recalls the boxer wearing a brand new box-fresh pair of Adidas sneakers to go on a shopping spree. 'I went with him to the Adidas store and he bought an identical pair of sneakers to the ones he was wearing.

'He handed that pair to the store worker and told me, 'I need another pair to go back to the hotel.'

Floyd is so worried about germs that he takes his own set of silverware to restaurants so he doesn't have to use theirs. He has gold ones, platinum ones, some with diamonds and with his initials FM engraved on them. We carried them around in a box we called the coffin.

'If he got the tiniest scuff on his shoes he'd throw them away. 'They always had to be perfect, bright white. It was the same with t-shirts, he didn't like to wear them again.'

Tasha says Mayweather would often check out of hotels and leave all his clothes and toiletries behind.

Tasha says Mayweather, nicknamed 'Pretty Boy' in the ring, is equally obsessed with keeping a perfect physical appearance.

He likes his body to be completely 'hair free' and shaves his whole torso every day as part of a two hour grooming routine.

The tough boxer has a 'mani and pedi' twice a week to keep his nails immaculate, two massages a week and he visits a dermatologist every six weeks for a chemical peel on his face and other treatments.

Mayweather's obsessive nature also spilled over in to his personal habits.

Tasha said the boxer had OCD over his cleanliness and was terrified of germs.

He has a housekeeper who cleans his home top to bottom every day and he stands over her making sure she does it properly.

He also has a member of his staff whose sole job it is to clean his fleet of luxury cars.

But the obsessive star refuses to drive any of the already spotless vehicles unless they have been 'freshly' sanitized on the day he drives them.

Tasha added: 'Floyd is so worried about germs that he takes his own set of silverware to restaurants so he doesn't have to use theirs. He has gold ones, platinum ones, some with diamonds and with his initials FM engraved on them.

'We carried them around in a box we called the coffin.'

Clean-living Mayweather also never drank alcohol or experimented with drugs, preferring instead to sip cranberry juice, coke or water when on a night out.

Tasha, originally from Saginaw, Michigan, first met Mayweather when she was a club promoter in Vegas in 1998.

Mayweather asked Tasha to work for him after being impressed that she could attract so many celebrities to her parties.

'He asked her to help set up his music label called Philthy Rich,' said Tasha.

'I liked him, he was respectful and pretty cool, I had some experience in the record industry so I thought why not.'

She claims in the early days Mayweather was 'a little wet behind the ears' and desperate to emulate the likes of 50 Cent and Jay-Z as a music mogul.

'Floyd aspires to be Floyd, but he wanted to be part of that scene, he wanted what those guys had,' said Tasha.

But his attempts to break into the hip-hop industry weren't very successful, mainly because of a lack of planning.

'We moved when Floyd moved,' Tasha said. 'We didn't have a plan and if Floyd was in the boxing gym everything would stop.

'I was enjoying my job, but nothing was the same from one day to the next.

Spending time: Mayweather would wonder why his entourage were asking for their salaries when he had paid them in Rolexes - just some of the watches in his collection. he once said it was worth $6.4 million

'My job responsibilities grew to include going to the bank with him to shuffle money off to people he was taking care of. He often put money on the books of friends in prison back in Grand Rapids, and across the country.

'We went everywhere together, he even added me to his auto insurance plan just in case I ever needed to drive one of his cars.'

In the latter days of their relationship Tasha was made CEO of Mayweather Music and Founding President of the Floyd Mayweather Jr. Foundation.

She was earning $8,000 a month with bonuses ranging from $20,000 to $100,000.

As their relationship grew Tasha became closer with Mayweather and was a trusted confidante.

But she says, the star had his ups and downs, and the money began to consume him.

'He's always had wealth, but he used to say, 'I'm a thousand-aire now but when I become a millionaire…' and when he became a millionaire he'd say 'when I become a billionaire…'.

'It just escalated and he'd always say more money more problems and that actually came true, I witnessed it first hand.'

The worst of his problems came in 2008 when Mayweather faced a series of financial disasters.

That same year the sportsman publicly announced his retirement from boxing - only to be sensationally duped by a conman called 'Three comma Joe' in an elaborate scam.

The alleged fraudster convinced Mayweather to hand over a staggering $15million to him for a get quick rich scheme.

Mayweather was told it would make him a $5 billion return. Unsurprisingly the man ran off with his cash.

Weeks later burglars robbed his luxury mansion in Vegas stealing an estimated $7million in jewelry alone.

The IRS were also chasing him for an unpaid $6.2 million tax bill.

Tasha said: 'It was a tough time for Floyd. The biggest blow was being scammed out of $15million.

'Floyd met with a group of middle-men who introduced him to a guy called Three Comma Joe.

'He was impressed by Joe, he came in with the flossy blonde girl, he wore a nice big icy watch, he had the flash and Floyd was like, 'that's my kind of guy'.

'After the deal was done they shook hands and began to hang out a lot, they were inseparable.

'Floyd wired $15million to a Canadian bank account and he was told to see a return very soon.

'But eventually Joe left Vegas and stopped returning phone calls, and the money train came to an abrupt halt. Nobody could find Joe, and no one could find Floyd's money.

'Not the $15 million Floyd originally invested, and definitely not the $5 billion he was promised to make in return. Life in the Mayweather camp got really nasty for everybody.'

Tasha tells how furious Mayweather hired a team of private investigators to look for Three Comma Joe.

Family: Author Tasha Robinson-White whose memoir 'Right Hand to the Champ', chronicles the twelve years she spent working for the Floyd Mayweather Jr, with her husband Kevin White.

And she says at one point he took her, his girlfriend and two burly security men on a failed mission to retrieve his missing cash from Joe's attorney's office in Vancouver.

By the time she stopped working for him, Mayweather had not seen a cent of the $15million.

Around the same time, in August 2008 Mayweather's home was robbed and the thieves stole $7 million in jewelry.

The series of events deeply affected Mayweather – voted the world's highest-paid athlete for 2011, 2012 and 2013 by Forbes - and he was forced to come out of retirement to 'maintain the lifestyle he had', says Tasha.

She said the money 'changed' Mayweather for the worse.

'He became that little bit more controlling, he became like a spoiled child,' she said.

'He would say, 'I can do it my way', 'I wanna do it this way'. He wasn't as humble as when I first met him.'

In one of his darkest moments Tasha says he kept his girlfriend 'captive' in his home for two days.

The paranoid boxer became suspicious that a then girl was somehow behind the robbery and he had also learnt she had slept with one of her ex-boyfriends behind Mayweather's back.

He kept her inside his movie room for two days as he berated her with the accusations, Tasha claims.

Tasha said: 'When I returned to the theater room, Floyd was still pacing and hollering incoherently. He instructed his security guards to camp out in front of the door.

'In the room, Floyd was very domineering. I was now not only concerned for his state of mind, I was growing concerned that this woman was being held against her will.

'He taunted her to try to leave. She appeared to be frightened and confused. He threatened to cut off all of her hair, and let the crew take turns with her.

'She didn't say anything. She kept her eyes fixed on the floor. We were in a circular argument that kept branching, and branching. I pulled Floyd aside and told him to try to calm down.

'He had to let [her] go home if that's what she wanted to do.'

But Mayweather's lowest point came a few months later when he got into a domestic dispute, assaulting the mother of three of his children in 2012.

Tasha says he discussed with her his plans for death and his funeral arrangements including which custom suit he wanted laid out on his bed to wear and how Tasha had to tell his four children he loved them. 'This is not gonna end well,' he told a concerned Tasha.

'I was very concerned for him, he was crying and in a dark place, I've never seen him like that.'

His ex-girlfriend, Josie Harris, said that Floyd flew into a violent rage once he learned she was dating another man, stole her cell phone and beat her, in front of their children.

If convicted of all eight charges, Mayweather faced up to 34 years in prison.

'That would qualify as not ending well,' said Tasha. He eventually served just 60 days inside.

Tasha had ended her working relationship with Mayweather in April, 2009 after she began to feel certain people within his entourage were blaming her for the $15million fraud, but the two remained friends.

'I wasn't going to take that,' she said.

'Working for Floyd Mayweather eventually broke my spirit but I didn't dislike him.

'I believed in him, we believed in a lot of things we were building together, but the elephant in the room was money.

'To me money isn't everything, to him it was.'

After they parted ways, Tasha's father died after a battle with lung cancer.

Mayweather called her to offer his condolences and offered to pay for the funeral.

He gave $9,000 to Tasha as a gift to cover the ceremony which she thought was very kind of him.

But on the day of her father's funeral in a move that shocked Tasha, Mayweather had his associate ring her and ask for the money back which caused her great distress.

'It hurt me, it all boiled down to $9,000 which I knew he didn't need. I still haven't put my finger on why he did it, I just thought it was really mean.

'Floyd likes it his way, he likes to be in control.'

Tasha recently spoke to Mayweather about her memoir and he told her: 'Write whatever you want, it keeps me relevant.'

She said: 'He knows he has always been a villain to a lot of people and he likes to play up to that.'

Representatives for Mayweather did not respond to requests for comment.
