Not everybody is a fan of Adam Levine. Or Maroon 5. Or "The Voice".

On his way out of a performance on the set of Jimmy Kimmel Live! yesterday evening in L.A., Maroon 5 frontman Adam Levine was signing autographs for fans, minding his own business, when he was pelted with a "sugar bomb" by a man. It happens at :57.

“It looked like he wanted to fight the guy,“ an eyewitness said of Levine’s reaction. “It was a brown bag with tape around it, which was weird. I just saw powder everywhere. It was just so quick.“ Levine, of course, is responsible for the hit song “Sugar,“ while the suspect, a man believed to be in his thirties, was tackled by security and subsequently arrested.
