Her performance will be huge
What I've seen of it is great. She'll be dancing, performing, doing her thing
Britney knows she's on thin ice. When they agreed to the performance, they sat her down and told her she should not be going out, and instead focus on rehearsing and resting
That's exactly what we all want.
She seemed to be thankful and appreciative for the chance, but who knows with her? MTV made it clear that her usual behavior will not be tolerated.
She's totally phoning this in. She doesn't seem to care how this goes. She's been drinking a bunch and not putting her all into rehearsing.
