Amy Winehouse feels too ugly to attend her own birthday party

London, Sep 15 : Troubled popstar Amy Winehouse is shocked to see how drugs have ruined her looks, and she even refused to attend her birthday party because she felt she looked pretty ugly.

Although Winehouse's pal Remi Nicole had organized a huge bash for her, she was adamant on not attending the party.

The 'Back to Black' hitmaker ranted "I look "f***ing ugly", as she stood in front of the mirror.

Though three cabs were called at her Camden home, she did not agree to attend her birthday party.

After much convincing Winehouse and a huge row, Nicole took the third cab home.

"Amy was standing in front of the mirror telling everyone how rough she looked, unfortunately her lifestyle has had a major affect on her appearance and it's only just started to sink in," British tabloid The Sun quoted a pal as saying.

"She kept saying she was ugly and was in an awful state, they couldn't get her out, Remi had organised the night and made a huge effort. They had a huge row," the pal added.

The guests at Winehouse's party including Adele, Mark Ronson and Amy's mother Janis were left with no choice but to eat her guitar shaped cake without even seeing the birthday girl.

"Amy can be very selfish - there was no convincing her and she ruined the night for everyone, including herself," the pal said.
