Britney Spears is set to perform at the 2009 Teen Choice Awards. The "Womanizer" singer - who is nominated in three categories - will appear on stage at the annual event on Sunday night at Universal City's Gibson Amphitheatre, in California.

Her performance will mark 10 years since the first Teen Choice Awards in 1999, where Britney - who is currently on a break from her world tour - was one of the performers.

Robert Pattinson insists fame hasn't changed him. The British actor - who first appeared in "Harry Potter and the Goblet of Fire" but achieved worldwide recognition playing vampire Edward Cullen in "Twilight" - insists his life has stayed the same, despite his legions of female fans.

He said: "I'd like to think that I haven't changed that much. Within myself, I don't think I've changed. When I'm walking down the street, I look down a lot more often. It seems to keep building, the magnitude of this franchise."

Robert Pattinson has lost his car.

The 'Twilight' actor Robert Pattinson can't recall where he left the vehicle, despite it being incredibly important to him, after his hectic filming and travelling schedule left him disorganized.
