Adam Levine was sugar-bombed in Hollywood on Wednesday evening as he arrived for a TV talk show appearance. The Maroon 5 frontman was greeting fans outside the Jimmy Kimmel Live studios when a prankster ran up to him and threw a bag of powdered sweetener all over the singer. An angry Levine was ushered into the studio, where he cleaned up in time for his appearance on the late-night show. Security staff nabbed the attacker, who police later arrested. It is not clear why he attacked the singer.
