Ant McPartlin's estranged wife has revealed her heartbreak as it emerged that the TV presenter had found love again with his personal assistant.

The troubled star is believed to be seeing Anne-Marie Corbett, 42, after she stood by him following his marriage break up and drink driving shame.

Ant's new relationship is believed to have rocked make-up artist Lisa, who tweeted a broken heart emoji at 5am this morning, hours after the news was first revealed.

The 42-year-old announced his separation from Lisa earlier this year, with the pair filing for divorce in January.

Since the breakdown of the couple's relationship, Ant has increasingly leaned on personal assistant Anne-Marie, who herself broke up with her husband in October.

Anne-Marie was present when Ant arrived at a police station in March to answer drink driving charges, and was also at his later court hearing.

A source told The Sun on Sunday: 'He's had a tough time of it, but Anne-Marie has put a smile back on his face again - she has been his rock.

'They have been living in each other's pockets, day in, day out.

'Knowing someone is there for him has brought him back from the brink — she's put him back together again.'

The source added their alleged romance was 'early days' but friends close to the star are hoping he can put his woes behind him and 'find happiness again' with the separated mum.

MailOnline has contacted Ant's representatives for comment.

Just last week, Ant looked in high spirits as he was seen indulging in a spot of retail therapy with his PA at Harrods, Knightbridge.

The television host emerged from the famous luxury department story and headed to an awaiting vehicle with Anne, who was joined by her two young children, who she shares with her ex-husband Scott.

Anne-Marie has been employed by the same London-based management company as Declan Donnelly's wife Ali Astall for ten years but began working closely with Ant only recently, according to The Sun.

Duo: His casual sighting at Harrods with Anne comes after Simon Cowell said he wants Ant to return for the next series of Britain's Got Talent

His rumoured romance comes after Simon Cowell said that he wants Ant to return for the next series of Britain's Got Talent.

BGT's live final and semis went ahead without Ant for the first time in the show's 11-year history.

Simon told The Sun: 'It's a wake-up call. It's as simple as that. Maybe the pressure was more than I realised. I will support Ant when he comes back.

The music mogul, 58 has vowed to put psychiatrists in place to support him, after admitting he didn't appreciate the pressure he was under before the rehab stint.

Ant stepped down from his presenting commitments when he was charged with drink-driving following a three car crash.

He was fined £86,000 and banned from the road for 20 months, after he was caught more than twice the legal limit following a crash in Richmond in March- with his mother in the car.

The presenter pleaded guilty to driving with 75 micrograms of alcohol in 100ml of breath, after his involvement in a three-car collision. The legal limit is 35 micrograms

McPartlin was arrested after losing control of his black Mini and smashing into two other cars, a Mini and a BMW, while driving in Richmond, west London on March 18.

The crash came after he formally announced he was divorcing his wife Lisa Armstrong after 19 years together.

Their decision to get divorced was announced in January, within weeks of the presenter's return from Australia after filming I'm A Celebrity... Get Me Out Of Here!

Ant's spokesman said at the time: 'In response to the recent speculation in the media, Ant is very sad to announce that, after 11 years, he is ending his marriage to Lisa McPartlin.

'Ant asks for privacy at this difficult time, for both himself, Lisa and their immediate families. No further statement will be made.'
