Emma Stone presents a surfboard award onstage at the 2011 Teen Choice Awards held at the Gibson Amphitheatre on Sunday (August 7) in Universal City, Calif.

The 22-year-old actress stepped out in a Christian Dior dress, paired with Lanvin heels and jewels by Irene Neuwirth to present Taylor Swift with the Ultimate Choice Award.

Justin Bieber shouted, “I love you” when Emma walked out — as he was sitting next to girlfriend Selena Gomez!
