Gregg Wallace reveals his daughter Libby, 28, has got engaged

Gregg Wallace has announced his daughter Libby is engaged to boyfriend Alex Marsden on Instagram on Thursday. 

The MasterChef star, 60, shared the exciting news with fans that his only daughter, 28, is set to tie the knot with her boyfriend of two years. 

Libby showed off her dazzling engagement ring in a sweet post surrounded by pumpkins and gushed that Alex had got down on one knee in the 'most magical place on earth'. 

She wrote: 'I said yes in one of the most magical places on earth #PumpkinProposal'

It comes week after the happy couple celebrated their two year anniversary together and shared a gallery of snaps to social media.

Libby penned: '2 years of us, my love ❤️ In 2 years we have had 3 house moves, 2 trips to urgent care and countless belly laughs. 

'Here’s to more adventures, silliness, taking things too far and just generally more chaos. I love you'.

Gregg shared Libby and son Tom, 30, his son from his second marriage to pastry chef Denise, who tragically died in 2017 following a tough battle with alcohol addiction.

The former couple married in 1999 and divorced in 2004.

Gregg and fourth wife Anne, 39, who he married in 2016, welcomed his third child, a son Sid in 2019.

The BBC star and Anne-Marie, who is 22 years younger than him, tied the knot at Hever Castle in Kent in August 2016, having met three years earlier. 

It comes after Gregg revealed he would 'never' renew his wedding vows with his wife Anna. 

Gregg told MailOnline that despite being 'an expert' in weddings, he would never renew his wedding vows to Anna.

During the interview, Gregg, who has walked down the aisle four times, explained: 'No! I've never really understood that. We’ve had our wedding day, and it was a big celebration. 

'I feel like you'd be diluting your wedding day if you kind of did it again. And I know all about weddings as well. I'm an expert.'

It comes after Gregg denied claims he boasted about his sex life to a younger female BBC employee and took his top off in front of her while filming a game show - saying he would never 'flirt with' or 'hit on' another woman.

Bosses at the corporation are said to have hauled the MasterChef co-host into a meeting in 2018 following allegations of 'inappropriate sexual comments' and told him to 'change his behaviour'.

An insider claims Gregg brushed it off as 'just banter', having been reported for making 'consistent inappropriate comments' to the member of the production team while working on game show Impossible Celebrities.

But taking to Instagram, Wallace hit back at the allegations in an emotional video saying he was 'madly in love' with his wife Anna.

He said: 'The story that's hitting the newspapers this morning was investigated promptly when it happened six years ago by the BBC.

'And the outcome of that was that I hadn't said anything sexual. I'll need to repeat this again. I didn't say anything sexual.

'Despite what the newspapers are suggesting nobody six years ago accused me of flirting with anybody or hitting on anybody.

'And the reason I say this is because of my wife Anna. I have always been true to my wife Anna and have never flirted or hit on anybody in the 12 years [since] I met her and fell in love with her.

'And it's important that, so that people don't misunderstand that, that I am true to my wife.'
