Booboo Stewart and Fivel Stewart: What Makes the Twilight Cast Smile

Booboo and Fivel Stewart were on the Teen Choice red carpet working with Invisalign. They asked celebrities who they thought should win the Teen Choice Best Smile Award (it was won later that night by Taylor Lautner) and what personally makes them smile. They spoke with Justin Chon, Charlie Bewley, Bronson Pelletier, Alex Meraz, and Kiowa Gordon.
