Everyone’s favorite unapologetic alcoholic, Amy Winehouse, canceled another show on Thursday at the last second according to New Musical Express. Though she rescheduled, it left 4,500 a little more than irate.

After waiting for hours in the rain in Liverpool, fans were told Winehouse was too ill to perform, even though they had heard her warming up backstage.

According to Yahoo Music, she’s been diagnosed with “exhaustion.” Boozing too much and forgetting your vitamin C will do that to you.

“Winehouse pulled out of the 4,500 capacity gig at the eleventh hour, leaving thousands of fans hanging in the rain outside. It’s thought she was sent to hospital for treatment.

Now, Summer Pops organisers CMP have left an official statement on their website which reads: ‘Following Doctors advice, Amy Winehouse was unable to perform at the Summer Pops concert.

‘We would like to apologise to all fans for this cancellation and are pleased to announce that the resceduled Summer Pops show will now take place on Wednesday July 18th 2007. Tickets will be valid for the new date or a full refund is available.’

Many fans have been speculating that the booze-loving star had axed the show after another notorious drinking session.”

Her wild antics are no secret. She ran off and got married without any warning, cut her husband’s initials into her stomach with a shard of glass in front of a reporter, and has been seen out habitually drunk.

Amy Winehouse has an amazing voice and very cool style, but every time I see her I can’t help but wonder how she keeps that massive (and I’m assuming sort of heavy) beehive atop her head when she looks so emaciated. It seems like she’s really committed to living the dramatic, tragic musician experience. I hope she gets her act together, or people won’t be willing to stand in the rain for her.
