Funnyman Jonah Hill stole the attention from Justin Bieber at the Espy Awards in Los Angeles on Wednesday night (13Jul11) with his stunning weight loss.
The once-chubby star hit the red carpet looking slender, wowing reporters and bystanders who didn't recognise the new-look writer/actor.
Asked what inspired the transformation, Hill said, "I just went to see a nutritionist and I wanted to be healthier. I started running and stuff."
