Jonah Hill: 'Good Time Gang' with Mark Wahlberg!

Jonah Hill kisses his longtime girlfriend, Jordan Klein, after stopping by the Brentwood Country Mart on Sunday (July 17) in Santa Monica, Calif.

Last week, the 27-year-old comedian showed off his new slimmed down body at the ESPY Awards!

Jonah, who’s co-starring in Moneyball and 21 Jump Street, has signed on for another project.

He’ll “play one half of a bumbling pair of antiheroes in the action comedy Good Time Gang with Mark Wahlberg playing his partner,” the L.A. Times reports.

FYI: Jonah is wearing Hoyle Jackson pants.
