The Twilight star teamed up with Tom Cruise for a spoof video ahead of the June ceremony.
Cruise stars in the clip as his Tropic Thunder alter ego, Les Grossman, complete with bald head and bulging tummy.

As the foul-mouthed movie mogul, Cruise issues some rather colourful advice to Pattinson, who begins the clip by discussing his plans to overhaul his scruffy look for the awards.
Pattinson says: 'I'm thinking about cleaning up a little bit, maybe get a suit, have a shave, maybe wash my hair.'
In full Grossman mode, Cruise tells the star he'll arrange a hairdresser to give him a blow wave, before adding: 'And then I'll give you the number of a good plumber because you've just flushed your f****** career down the toilet!
