Jonah Hill is spotted on the set of his new film 21 Jump Street in New Orleans on Wednesday (May 4). Ice Cube was also spotted on set on Wednesday (pics in gallery below), as well as Channing Tatum (pics here).
Jonah isn't just starring in the film - he actually wrote it, too. According to reports, he lost 30 pounds to play the role of an undercover cop infiltrating a high school. A pal of his told Us Weekly:
"[Jonah] went on a diet for the movie, but gained weight at first! Finally, he got a nutritionist and a trainer. Now he looks better and feels better!"
Congrats on the health transformation Jonah!
