Adam Levine had a serious sense of humor failure (not surprisingly) after some loon threw a shit ton of sugar in his face last night.

It all went down as the 36-year-old was leaving Jimmy Kimmel’s studio after performing with his band Maroon 5—and you can watch the video right here on Popdust.

Levine was graciously meeting and greeting the throng of fans outside when the sugar bomber attacked, hitting the singer bang smack in the face.

For one minute it totally looked like Levine was going to punch the shit out of the dude, but instead, sanity prevailed and he stormed off instead.

Laura Tijerina, who was waiting for an autograph as the bombing went down, told CNN, "It looked like he wanted to fight the guy.

“I think this guy had it planned. It was a brown bag with tape around it, which was weird. I just saw powder everywhere. It was just so quick."

Yeah, I think it’s safe to say that he had planned it, and wasn’t just on his way back from the supermarket with a giant bag of sugar.

In fact, turns out the dude has a history of attacking celebs—Navid Farsi, 28, previously threw a rock at The Rock, and has three other pissed off victims too.

Farsi was arrested at the scene and hauled off by the LAPD. He’s currently in jail pending $100,000 bail and now has a grand total of five battery charges against him pending.

Meanwhile, this is the second time Levine has been attacked in the past month.

As Popdust previously reported, last month poor Adam was assaulted by an over zealous lusty lady fan, who was presumably overcome by Levine's sexiness, rushed the stage and grabbed him in a passionate clinch.
