Don't Miss:

These couples know how to Do Something together! Last night’s Do Something Awards in Santa Monica boasted a red carpet of go-getting doers, including cute on- and off-screen celebrity couples like Hit & Run’s Dax Shepard and Kristen Bell (in Jenni Kayne), Glee’s Cory Monteith and Lea Michele (in Giorgio Armani), and Giuliana & Bill’s Giuliana (in Cengiz Abazoglu) and Bill Rancic. All were on hand to be a part of dosomething.org’s mission of honoring the top world-changers under 25 with grants (winners also take home the Do Something Silver Shoe, which looks like the Jeremy Scott for Adidas wing sneakers). Tune in to watch the Do Something Awards on Vh1, Tuesday, August 21st at 9/8c, and click through to see more stars (and what they wore) to the feel-good event.
