Amy Winehouse Headbutt

After partying until 4:00 am in a London pub on April 23, 2008, Amy Winehouse allegedly headbutted a man in the face during a heated argument. According to an onlooker, Winehouse became upset and headbutted and punched the man outside of the pub she was patronizing. Winehouse's friends reportedly forced the singer back into the pub after the brawl.

Winehouse has been in the forefront of the media lately because of her drug abuse. She was arrested for possession of marijuana in 2007. On January 22, 2008, Winehouse entered rehab after the release of a video by The Sun newspaper that depicted her smoking crack.
