George Clooney plays cruel pranks on dieting co-stars

George Clooney has confessed that he plays cruel pranks on his co-stars who are on diet.

The 52-year-old actor, who is well known for his practical jokes, said that he does enjoy whenever an actor is trying to lose weight having the wardrobe people take in their clothes, the Mirror reported.

The 'Ocean's eleven' star said that it just makes him laugh, watching them eating a grape the next day and they do it for weeks, so it's good fun.
