Robert Pattinson and Kristen Stewart and a whole slew of the Twilight stars are expected for the third time at tonight's Teen Choice Awards. The cast is up for 12 awards, so it's probably smart that they have enough stars to rotate trips to the stage!

The cast won 12 awards last year, and we're guessing they'll come close again in 2011. How could they not? Everyone loves the vampires and werewolves -- and RPattz and KStew are sure to win the best liplock prize! They did so at the MTV Movie Awards two years in a row, after all.
This year Robert and Taylor Lautner are up against each other for Choice Male Hottie, and a slew of other prizes. But, they'll also be up against tough competition with teen heartthrob Justin Bieber up for a bunch of surfboards. Who will win big tonight? Tune in at 8 to find out!
