For all those Britney fans it looks like the exciting news about her surprise performance on Cyndi Lauper's True Colors Tour this weekend won't be happening. Turns out they actually wanted her to sing live. According to Page Six, "There's no way. Britney said she would only dance or lip-sync - and to be on stage with Cyndi, you have to actually perform. It's not happening now." Ouch. As harsh as it may be for Brit, we have to agree with Cyndi on this one - if Britney really wants to win back the hearts of her fans, she's going to have to step it up.
