Amy Winehouse was out partying until 4 am last night, and proving she could be part of the WWE. Amy got upset with a dude outside the club so she headbutted him and punched him in the face. Oh yeah! Crackhead anger at its best! Next thing you know she's gonna start throwing heroine syringes like a ninja!

Amy "got upset and lashed out, headbutting a guy hard in the face and also punched him," said the onlooker. "Her concerned friends rushed outside and dragged her back inside the pub." She then headed into a sweet shop and appeared to help herself to a paper, fags and sweets before racing back to a waiting cab. And then to Amy's surprise, she smacked her face into a lamppost.

After being dropped back at her London flat, the 24-year-old songstress infuriated one last bystander allegedly short changing the taxi driver $40, telling him his ride "wasn't worth it". She then realized she couldn't get back into her own home as her pal had her keys and money, so she prized open her garage door to gain entry.
