The `Behind Closed Doors` hitmaker - who has children Junior, five, and three-year-old Princess Tiaamii with ex-wife Katie Price - has made a pact with former girlfriend Elen Rivas to get in shape by using the tough fitness classes, though he is unsure when he will find the time to take part.
He wrote in his column for new! magazine: "Elen and I have decided that the next time we both have three days free without the kids, we`re going to hit bootcamp together! I`ve always wanted to try it and we came to the conclusion it`d be more fun to do it together. Who knows when it`s going to happen as our schedules are insane but I`ll tell you all about it when it does."
When Peter does start bootcamp, he will be hoping to take the regime more seriously than his friends Kerry Katona and Danielle Brown, who couldn`t resist tucking into their favourite fast foods before a recent session.
Speaking about seeing the pair at a party before they went to BootCamp, Peter said: "Kerry only stayed at the party for half an hour as her and Danielle Brown were driving off to bootcamp that night. It`s funny though as she phoned me about an hour after they left to say they`d stopped at Burger King for dinner! Nice one Kez, start as you mean to go on!"
