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."
