Britney Spears needs better handlers and better excuse makers. But, we all knew that.

The lame blame game that swirled yesterday is being countered with details of Britney’s bad behavior before the awards show.

She arrived in Vegas hours after a scheduled rehearsal, was partying when she should have been working, and wouldn’t listen to the pros putting on the show.

And then came the thud of a performance seen around the world.

Page Six is reporting:

"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."

Oh…but there’s more.

That unflattering costume? It was worn at Britney’s insistence because she thought it was "sexier" than what the professional were recommending.

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."

Wow.
