Underrehearsed, under the influence, under the weather: Why Britney blew it

In direct contradiction of the "it was the venue's fault" explanation for the Spears career suicide evening, the New York Post offers a more plausible-sounding explanation:

"She didn't even get to Las Vegas until 4:30 p.m. It was ridiculous [...]
"She went to her hotel room and ordered a bunch of food and some frozen margaritas," the spy said. "She came down, like, an hour later with a frozen margarita in her hand."
[...]
"The dance number was spectacular - without her," said our spy at rehearsal. "When the stand-in was rehearsing with the dancers, in the hours they were all waiting for her, it was amazing. Then Britney showed up and refused to do anything. The dancers were supposed to lift and twirl her in the air a few times, and that just wasn't going to happen. The more complicated dance moves had to be erased because she couldn't do them."

Another spy said, "The dancers were texting pals, asking them to pray for them. They were worried."

And it turns out that the bra and knickers was down to her forgetting to bother with a costume:

"MTV wanted her to wear a corset outfit. It would have looked great and covered a lot of things up, but she hated it and didn't think it was sexy enough."

There is, again, the dispiriting suggestion that Spears was somehow overweight - as if the real 'being fucked up' wasn't enough without adding some spurious '... and she's fat, too" element to it:

Spears changed into a spangly bra-and-underwear outfit she'd brought with her that emphasized her weight gain over the last year.

Ironic, given that her body shape is the only thing about Britney that has got healthier over the last twelve months.
