A Boozing Shame! Jonah Hill's Drinking Stirs Trouble For The Actor

Jonah, 32, has openly admitted that beer is his "Achilles' heel," but now it looks like other beverages are too!

Sources revealed that he's turned to alcohol, and it's causing a strain on more than his weight-loss progress.

"When he drinks, he eats a lot," an insider explained. "It's a vicious cycle that's threatening to undo all the progress he'd made."

"Jonah becomes obnoxious and mean when he drinks," the insider added. "He thinks he's being funny, but he ends up insulting people."

At an event in Los Angeles, Calif. with Channing Tatum, "Jonah was gulping down a cocktail. He was being really loud and laughing at his own jokes, and even though it was pretty cold in there, he was sweating."

Even though he gained all 40 pounds that he lost in 2011 back, Jonah's rep denies the Wolf of Wall Street actor has a drinking problem.
