Plenty was accomplished at the Do Something Awards on Sunday: A comeback performance from Demi Lovato, a healthy dose of Justin Bieber, a hosting dry-run for Emmys emcee-to-be Jane Lynch and some honoring of charitable youth all went down in Hollywood during the ceremony. The Do Something Awards, hosted again by "Glee" star Lynch, brought celebrities out to celebrate a young generation of leaders who care about causes such as special-needs kids, ending hunger and educating refugee children.

Backstage at the big show on Sunday, DoSomething 101 held its Backpack Party, where the likes of Zachary Levi and Nikki Blonsky packed school bags full of Staples supplies that will be donated to underprivileged kids in Los Angeles.

Instead of a gift bag that celebs merely scooped up for gracing the award show with their presence, this new bag was a collaboration between the TCAs, some of today's hottest young celebrities, DoSomething.org and Staples.
