Great British Bake Off host Paul Hollywood has described his affair with an American co-star as "the biggest mistake of my life."
He was widely reported to be having a fling with Marcela Valladolid, co-judge of The American Baking Competition, but had never previously spoken about it.
He told BBC Radio 5 live's Richard Bacon: "It was the biggest mistake of my life - because actually I still love my wife [Alexandra]. We are talking, working together but it's going to take time.
"I was shocked about the whole thing kicking off the way it did... but I deserved it and I've taken it. It was my punishment."
The winner of the BBC's Great British Bake Off has said she is surprised by the huge amount of attention and controversy the programme has attracted on social media.
Frances Quinn told Radio 4's Today programme: "I'm just so glad it wasn't actually going out live; having to go down there and film over a weekend knowing what was going on in the press and social media".
She said that she and the other contestants all got on well, even though "everyone is wanting to make out that we didn't".
One of the finalists in last night's Great British Bake Off has said she is surprised at the "nastiness" and "misogyny" generated by critics of the TV show.
Writing in a comment piece in The Guardian, Ruby Tandoh said: "Despite the saccharin sweetness of the Bake Off, an extraordinary amount of bitterness and bile has spewed forth every week from angry commentators, both on social media and in the press."
Tandoh, 21, made the comments after a heated Twitter spat with the chef Raymond Blanc who criticised the show's "female tears".
"I don't care if you're a patisserie king - don't be an idiot," Ruby hit back.
She added in her article: "If a show as gentle as Bake Off can stir up such a sludge of lazy misogyny in the murky waters of the internet, I hate to imagine the full scale of the problem."
