Britney preformar ekki í nótt segir umbin hennar en hún kynnir

We got our hopes up, only to have them CRUSHED.

But, this is probably for the best.

PerezHilton.com just spoke to Britney Spears' manager, Larry Rudolph, and he tells us exclusively that the former and (hopeful) once-again Princess of Pop is NOT performing at the MTV Video Music Awards on Sunday.

She is 100% not performing, Larry assured us, but she will be attending and opening the show.

Rudolph has repeatedly stated recently that Spears was NOT performing, a statement echoed closely by the reps at MTV.

So, what to make of that on Friday that showed Britney rehearsing to a new song of her with some dancers???

"She was not rehearsing for the VMAs," Rudolph tells us. "It was just her going into the studio with some dancer friends and having fun. It's a regular occurrence now. I see that every day."

But we don't! And we got VERY excited.

Well, we think it's wise that Spears wait until she's 110% ready to perform and make a killer comeback.

But, Larry tells us, that day is not too far away!
