The daughter of rocker Ozzy Osbourne dropped several dress sizes after competing on U.S. reality show Dancing With The Stars in 2009, and she has continued with her healthy diet and exercise regimen.
Now she is teaming up with producers behind U.K. TV show Daybreak to find three tubby Brits in need of a body makeover.
Osbourne will fly the trio out to Hollywood next year (13) and introduce them to a team of personal trainers, dole out nutritional advice, and help them create diet plans.
She says, ""There is no quick fix. It's not just about losing weight. Nothing comes easy. You've got to want it. That's why I really want people to enter this competition who really do want this life change. It can be really fun, but at the same time it sucks! But you've got to learn to like it. I'm not going to torture anyone, I'm going to make it really fun.
""For me, food became a bit of an emotional thing. I punished myself with it. But I also was very uneducated about how to eat properly and what was good for my body and what times of day are appropriate to eat. It's amazing now that I can share everything that I have learned with everyone else.""
Entrants in the U.K. can submit applications via the Daybreak website.
