Reports earlier this month claimed that MTV bosses wanted to give the star a chance to make amends for her disastrous appearance at the 2007 ceremony. Spears's performance of 'Gimme More' at the event was branded an "embarrassment" by critics last year.
However, the singer's manager Larry Rudolph told Ryan Seacrest's radio show that Spears "is in the middle of recording her next album, which is going amazingly well, and was never supposed to perform at that show".
He added: "Britney Spears will not be performing at the VMAs this year. I'm telling you
officially and unequivocally."
The ceremony will take place on September 7. Spears has been nominated in the Best Female category, while the clip for her track 'Piece Of Me' is up for the Best Pop Video award.
