Britney Spears At VMA

Behind the VMA: when she arrived in Vegas, Britney didn't go straight to rehearsals.
"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 an onlooker. "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."
Meanwhile, Spears was agitated because she didn't like the outfit MTV had selected for her. "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." Instead, Spears changed into a spangly bra-and-underwear outfit she'd brought with her that emphasized her weight gain over the last year.
