At the UK's MOBO awards on Wednesday, Amy Winehouse partied until she puked - literally. The troubled signer won the award for Best UK female and celebrated the victory in her dressing room. But when her celebration got out of hand, she left the mess for someone else to clean up.

A witness to Amy's dressing room aftermath told the Mirror's 3AM Girls, "It was such a shocking and sad sight. The bathroom in her dressing-room smelt really bad. The toilet lid was still open and, well, how should I put this...it hadn't been flushed away. The floor was a mess too. It was such a shame to see."

During the MOBOs, Winehouse performed and forgot some of the words to her song, "Tears Dry on Their Own." Apparently she forgot that the toilet doesn't flush on its own either.

Uneaten food and unopened bottles on wine were sprawled across the room. There was a plate of Caribbean rice and peas and jerk chicken and two containers of spicy chicken stew.

A source for the Sun claims Amy was in a state all night. The snitch said, "In her dressing room she was really on edge, then flipped. She was screaming and chucking anything she could get her hands on at the people around her."
