Seth Rogen's Tearful Diet

Seth Rogen has tantrums when he can't eat.

The 'Knocked Up' star has shed 30lbs for his role in new comic book adaptation 'The Green Hornet' - in which he plays the crime-fighting vigilante of the same name - but doesn't think he will be able to maintain his new slimline figure when filming ends because dieting has made him so emotional.

I lost the weight for a role, but I don't know if I'll keep it off
He said: "I lost the weight for a role, but I don't know if I'll keep it off. That's the big question. I have a lot of tantrums. I want my food. I cry for no reason."

The actor is adamant he wouldn't have lost the weight if the role didn't require it and admits he feels like a "sell-out" for trying to alter his body shape.

He recently said: "I'm selling out guys. It's the lamest thing ever. It's for 'The Green Hornet' - the only reason. There's no other reason. I think it serves the movie."

Despite winning praise for his new figure, Seth has previously insisted his long-term girlfriend Lauren Miller is indifferent about his new look.

He said: "She's stuck by me through thick and thin - literally! She claims she doesn't like me any more now than when I was heavier, but I think that's completely not true."
