Kelly Brook is hoping co-star Keith Lemon's ego does not get bigger despite his ever-growing fame and up coming movie.
Kelly plays the leading lady in Keith Lemon: The film, and joined him at the world premiere in London on Monday night.
"I really hope all of this does not go to his head," she said.
He has a lovely girlfriend, Rosie, and already I can see it is getting carried away with all the girls down here, you know what men are like."
Keith Lemon: The Film hits cinemas on August 24.
