A star-studded press conference for this Sunday's MTV Video Music Awards took place today at the Paramount Studios in Hollywood, California. There it was announced that:

* Christina Aguilera will perform her new single 'Keeps Getting Better', from her forthcoming best-of collection of the same title (due November 10th in the UK and a day later in the US). Speaking on what to expect from her showing, Aguilera said: "You're going to get a first look and a first listen at my new image and my new sound," she said. "The last album, the style and sound was about vintage glam — this one is all about the future."

* T.I. confirmed that he will, indeed, be performing new single 'Live Your Life' with Rihanna at the show.

* Kanye West will be closing the show.
