Jonah Hill, who has notoriously played an overweight underdog in several films, has regained the weight he lost for "21 Jump Street."

We spotted the actor showing off a fuller figure as he pumped gas in Los Angeles on Sunday. Hill wore a half untucked button down shirt and dark jeans.

The actor lost 30 pounds for "21 Jump Street" by employing a nutritionist and personal trainer. He told Starpulse in the fall, "I run and do a lot of push-ups and eat healthy." Has he gotten off his fitness plan? Or perhaps he needs to regain the weight for a future film?

The actor just landed a role in Quentin Tarantino's upcoming film "Django Unchained." He also stars in the upcoming films "The Wolf of Wall Street," "The Adventurer's Handbook" and "End of the World."
