Soul superstar Amy Winehouse turns "violent and abusive" after too much alcohol and often attacks new husband BLAKE FIELDER-CIVIL. The Rehab singer admits she becomes aggressive after drinking alcohol and uses her husband as a "punch-bag" - but insists she is "not a fighter". She says, "I'm either a really good drunk or I'm an out-and-out s**t, horrible, violent, abusive, emotional drunk. "I'll beat up Blake when I'm drunk. I don't think I have ever bruised him, but I do have my way. If he says one thing I don't like then I'll chin him. "I'm not a fighter, but if I am backed against the wall I'll kick the s**t out of anyone. "I don't think your ability to fight has anything to do with how big you are. It's to do with how much anger is in you."
