Davina McCall has admitted she has checked up on her husband by secretly looking at his Facebook page.

The TV presenter, 43, who is married to former Pet Rescue host Matthew Robertson, said she didn’t feel confident enough about herself.

She told Zest magazine: “Oh my God I get so insecure! I checked my husband’s Facebook page – never do that! There was a flirty message from someone saying ‘I hear you’ve split up from Davina.’

“I had to fess up; I said ‘I’ve been a bad wife and I feel awful’ and Matthew told me what I already knew – that he hadn’t replied and he never would.”

The Million Pound Drop presenter said on ageism in the TV business: “There’s an enormous pressure on all of us, not just me on telly, but all of us to look younger. But I’ll continue to look after myself physically, staying fit and active. I do think that 50 is the new 40.”

Asked whether she’d go under the knife, she said: “I can’t say I’m not going to have surgery ever because I might be tempted. I have to be honest, but I think it’s a slippery slope, once you start, where do you stop?”
