The ceremony will include a tribute to the 29 year-old, but MTV executives have yet to comment on what it will involve. However, TV producer and casting director Jonathan Woodbeck has tweeted what he thinks will happen at the show.
He wrote: 'If this lineup is legit [which I'm told it is] the tribute to Britney at the VMAs is gonna be insanely EPIC!!'
Woodbeck then listed all the artists along with the Spears tune they will perform on the night as part of a medley.
Selena Gomez will be performing Baby One More Time, Perry will sing Oops! I Did It Again, is to tackle I'm A Slave 4 U, Demi Lovato will sing Toxic, Ke$ha and Nicki Minaj are thought to be performing a duet of Gimme More, Lady Gaga will take on Circus and Spears will perform a mash-up of Hold It Against Me/I Wanna Go.
Madonna will then apparently present Spears with a Lifetime Achievement award.
MTV has yet to confirm or deny the reports.
The MTV Video Music Awards is set to take place at the Nokia Theater in Los Angeles on August 28.
