Gregg Wallace is worried that Strictly Come Dancing judge Craig Revel Horwood is out for revenge.
The professional dancer took part in MasterChef back in 2007 but was criticised by Gregg, who's now scared that his dance moves will be slammed by Craig on the dance contest.
Gregg explained: "The irony isn't lost on me that I'm a judge on one show and now going to be judged on another, and Craig was on 'Celebrity MasterChef'.
"I'm trying to rack my brains to think back to what I said to him. I keep trying to replay his dishes over and over in my mind."
The presenter has shed a lot of weight since he appeared for the first time on the cooking show, but admits he's struggling to get the hang of his and partner Aliona Vilani's routines.
Writing for the Daily Telegraph he said: "There are a lot of moves I'm not used to doing as a greengrocer.
"I woke up with one completely knotted right calf and an aching muscle where I didn't know I had a muscle near my left hamstring."
He doesn't have plans to eat clean however.
"I think we can eat what we want. I lost three pounds in two days of training!
"I'm ambitious but I don't think I can win really, considering some of the younger, fitter contestants. It's not possible.
"Pixie [Lott] is just incredible and so is Frankie [Bridge]."
