The 2011 MTV Video Music Awards will include a tribute to pop star Britney Spears, and now one source claims that Katy Perry, Kesha and Lady Gaga will be a part of the all-star salute.

According to DigitalSpy, TV producer and casting director Jonathan Woodbeck ('The Real World,' 'Top Chef') has tweeted his prediction for the show. "If this lineup is legit (which I'm told it is) the tribute to Britney at the VMAs is gonna be insanely EPIC!!," he wrote along with a list of pop stars who are reportedly performing an unforgettable medley.

According to Woodbeck, the mash-up will include Selena Gomez singing '…Baby One More Time'; Perry performing 'Oops!…I Did It Again'; Janet Jackson fronting 'I'm a Slave 4 U'; Demi Lovato sampling 'Toxic'; Kesha and Nicki Minaj performing 'Gimme More'; Gaga singing 'Circus'; and last, but not least, Spears closing things out with 'Hold It Against Me'/'I Wanna Go.' Madonna will reportedly take the stage after the performance to present Spears with a 'Lifetime Achievement' award.

While this mega-medley would be a dream come true, MTV has neither confirmed nor denied the reports. The annual awards show has pulled off some unbelievable stunts in the past, so this A-list lineup isn't out of the realm of possibility, but we're still waiting for the final word from the network before we start jumping for joy.

The 2011 MTV Video Music Awards will air live from the Nokia Theatre in Los Angeles on Sunday, Aug. 28 at 9PM ET/PT on MTV and
