Pop/drunk/rehab/loser/vampire Amy Winehouse was arrested today in London for headbutting a poor dude outside of a London bar. She is likely to be charged with assault.

In the wee hours of April 23, the Grammy-winning “Rehab” singer allegedly headbutted a man outside a London pub. She voluntarily reported to a London police station on Friday to answer questions, and was arrested.
