He is known as one of reality's TV biggest lotharios, with a string of stunning conquests to his name and two children by a woman half his age.

But it seems millionaire Thomas Ravenel's allure may be on the wane after his latest girlfriend dumped him - and started dating a man living just two doors away from the reality star.

Daily Mail Online revealed that Southern Charm star Ravenel, 54, was seeing blonde socialite Nadia Bakalova after chatting her up in the self-help section at Barnes & Noble.

The aging playboy whisked 31-year-old Bakalova away on a series of fancy dates but friends say she was put off by the 'instability' in his life.

Bakalova has since moved on from Ravenel, and is dating 41-year-old Clay Olson, who lives just doors down from the reality star in Charleston, South Carolina

When their romance fizzled she grew close to mutual acquaintance Clay Olson, 41, a lawyer who lives in the same street as Ravenel in historic downtown Charleston, South Carolina.

The pair are already said to be dating and have not made any attempt to keep their blossoming relationship a secret from polo-loving neighbor Ravenel.

'Thomas is a lot of fun but he's just not ready for anything serious,' dished a source. 'Nadia met Clay through Thomas and really seemed to click. They are great for one another and she's very happy.

'Of course Nadia didn't set out to date one of Thomas's immediate neighbors but he knows all about it and seems genuinely pleased for them.'

Ravenel's dalliance with Bakalova also seems to have ended any hope of reconciliation with 24-year-old Kathryn Calhoun Dennis, his Bravo co-star and the mother of his two young children, Kensington and St Julien Rembert.

The mismatched couple have formed the central intrigue in Southern Charm, which follows the lives of party-loving southerners who flaunt their pedigrees amid the historic plantations and mansions of Charleston.

Their relationship was still intact after seasons one and two, but by the start of the third they had separated and were locked in a bitter legal battle over custody of their kids.

Daily Mail Online revealed last month how Ravenel had fallen for Coastal Carolina University graduate Bakalova, a real estate agent who is of mixed Bulgarian and Macedonian ethnicity but grew up in Virginia.

Ravenel is said to have struck up conversation with the statuesque blonde and asked for her number after he saw her buying a book about positive thinking.

Dennis responded by taking thinly-veiled swipes at Ravenel's womanizing on her Instagram account, where she posted none-too-cryptic comments such as 'Remember that time where you confused a life mate for a soul mate?'

But Daily Mail Online revealed that she too has quickly moved on by rekindling her romance with old flame Aaron Jones, 26, a marketing executive who lives in Charlotte Amalie in the US Virgin Islands.

'It's a tangled web for sure,' added our source. 'Charleston is a small place and there is every likelihood they will all bump into one another at some stage.'

Neither Olson, nor Bakalova, would comment on their relationship status but they can be seen cozying up together in a series of photos posted to social media.

In one shot Bakalova plants a kiss on University of South Carolina graduate Olson, who specializes in business litigation and defending personal injury lawsuits.

'I'm not a public figure and I can't see how I'm relevant to the story,' Olson said when reached by phone. 'I don't feel its an appropriate matter for me to talk about.'

Ravenel - nicknamed T-Rav by Southern Charm's viewers - is the son of former congressman Arthur Ravenel Jr.

He lives between a $2million, five-bedroom house in downtown Charleston and a sprawling plantation estate in Edisto Island, about 40 miles away.

Much of the second series of the reality show focused on Ravenel's attempt to win the Senate seat for South Carolina. He ran against Lindsay Graham but finished a distant third.

The Senate bid was an attempt to re-start his political career following his spectacular fall from favor in 2007 when - as State Treasurer - he was arrested on drugs offenses and later jailed for ten months.

A court heard he began taking drugs aged 18 and was seen using cocaine at numerous parties held in the Charleston area.

Dennis has political connections of her own and is a direct descendant of seventh Vice President of the United States, John C Calhoun.
