I couldn't help but clap when Grouplove performed at Teen Vogue's 10th Annual Young Hollywood Party last night. I love their song "Tongue Tied." I've been singing it all day long! To see who I ran into at the party, check out the Red Carpet Gallery. Congrats to Victoria Justice, who's on the October cover of Teen Vogue, the Young Hollywood issue), and to my Hunger Games castmates Willow Shields and Isabelle Fuhrman, who look gorgeous inside. If you go to the People Watching page, you'll see me talking about my fashion style. Here's a sneak peek before you go to the newsstand!
