Jake Gyllenhaal, Alan Sugar and Adam Lambert join Jonathan Ross for this week's Friday Night With Jonathan Ross on BBC One.

Jake Gyllenhaal says he enjoyed bulking up for Prince Of Persia: "When I got the muscles... I felt great."

He also tells Jonathan that he plays a viagra salesman in his next movie but doesn't need it himself: "I have no problems!"

Alan Sugar explains how he was inspired by the kids in Junior Apprentice: "It's really heart-warming to watch these youngsters, and says he has faith in younger generation: "It's going to inspire so many young people because they get a bad name, and this lot will bring confidence back in to the country."

American Idol's Adam Lambert says he remains defiant about controversial US TV kiss: "I felt it was really important not to make an apology, I stood my ground," and says how he wasn't fazed by Simon Cowell: "I respect his honesty, I like that. I didn't take it personally."

Finally, he tells Jonathan how he weighed 18 stone when younger and didn't get slim until he came out: "I was a porker, eating my feelings... I changed my habits, finally embraced who I was and felt better."
