Held to recognize the most charitable people, places and events over the past year, the winners of the 2011 Do Something Awards were crowned in Los Angeles, California on Sunday night (August 14).

When you've got a face and body like Olivia Wilde's you can generally do no fashion wrong. But the "Cowboys and Aliens" star came pretty darn close last night, donning a long pleated Chloe dress to VH1's Do Something Awards in Hollywood. The 27-year-old accepted the Do Something Movie Star award for her socially-conscious ways, beating out Kristen Bell, Orlando Bloom, Kathy Griffin, Scarlett Johansson and Daniel Radcliffe.

They joked last year that they were girlfriend and boyfriend before despite the 13 year age gap - and Justin Bieber and Kim Kardashian were reunited last night. However, in a neat twist, it now appears that the pair are in the business of matchmaking for other people. Kim, 30, and Justin, 17, were back together at the Do Something Awards last night and were pictured having fun together.

Oklahoma country music stars Reba McEntire and Blake Shelton have received a Do Something Award nomination for their pair of home state charity concerts that raised $500,000 for tornado relief efforts in Tushka. In addition, the hit NBC reality TV show “The Voice,” which features Shelton as one of its four superstar coaches and included McEntire among its first-season celebrity advisers, has been nominated for a Do Something Award.

DoSomething.org has announced the official voting period for the 2011 Do Something Awards opens today July 11, 2011 at 9am ET at DoSomething.VH1.com and extends through August 14, 2011 9am ET.
