Harry Potter may have beat them out with the number of Teen Choice awards won, but The Twilight Saga: Breaking Dawn stars were still a hit of the night! Robert Pattinson, Taylor Lautner, Kellan Lutz, Ashley Greene and Nikki Reed all attended last night's 2011 Teen Choice Awards. But Rob used his appearance for good by also raising awareness for the new "Cancer Bites" campaign.

Noticeably missing was Rob's girlfriend/co-star Kristen Stewart, who is busy filming Snow White and the Huntsman. Even without Kristen, it's still fun to see the cast reunited for an event.

Kellan dressed rather preppy for the night, Taylor wore his standard leather jacket ensemble, Ashley sported super straight hair and Nikki honored her fiancé Paul McDonald by putting his face on her nails!

But Rob also tried to have the focus of the night on something good and discussed a new campaign called "Cancer Bites" while accepting the award for Choice Vampire.
