According to OKmagazine.com, Britney was scheduled to perform but instead will just be giving a taped message.
"She was originally supposed to perform live and then she wanted to pre-tape her performance instead," a source tells OK!. "Then she didn't want to do that. She keeps changing her mind and now she's not performing at all but she is still supposed to pre-tape at 7 p.m."
