Jonah Hill And Channing Tatum Start Twitter Battle: Who Will Post New '21 Jump Street' Trailer?

Jonah Hill's upcoming "21 Jump Street" didn't just inspire a huge physical transformation, it's also lit his competitive fire.

In a kind of modern day popularity contest, Hill and his dreamy co-star Channing Tatum have taken to twitter to see who is "the better guy" and whoever emerges victorious (earning the most twitter followers) will tweet a Red Band trailer for the upcoming undercover cop remake.

"21 Jump Street" is a revamp of Johnny Depp's early 90's show about cops who go undercover in high school and colleges.

"It's a comedy with really cool action," Hill said in February. "We're not doing something serious like 'Miami Vice.' But it's not a parody. It's a funny movie with a lot of great action and a real story. I've been saying that it's like a John Hughes movie with 'Bad Boys' style action."

But for right now, they're facing off via social media.

Take a look at their opposing PSA's.

Presently, the star's twitter stats are 718,204 for Hill and 627,232 for Tatum.
