According to HitFix Robert Pattinson will not be presenting at the MTV Movie Awards. This does not mean that he won’t be present. Only that he’s not listed as a presenter up to now. Things can change.
Two days before the release of her new album “Bionic,” Christina Aguilera will be previewing some tunes at the2010 MTV Movie Awards. The pop singer so far is the only musical performance announced, while Aziz Ansari has been crowned host of the Los Angeles-based ceremony.
On tap as presenters are Tom Cruise, Cameron Diaz, Zac Efron, Jonah Hill, Jessica Biel, Bradley Cooper, Steve Carell, Miranda Cosgrove, Shaun White, Vanessa Hudgens, Sean “Diddy” Combs and MTV favorite Russell Brand. Absent from the list are the stars of “Twilight” – Robert Pattinson, Kristen Stewart, Taylor Lautner — whose presence dominated the broadcast (and the winners list) last year.
