The 2011 VH1 Do Something! Awards air this Thursday, August 18 at 9 p.m. ET. We’ve already shown you what everyone was wearing on the blue carpet tonight, but we have yet to pass along any of our sartorial assessments of who wore what. So, if your name is Tyra Banks, Adam Lambert, Zach Levi, Demi Lovato, Victoria Justice, Kim Kardashian, Amy Poehler, Charity Shea, Dax Shephard or Olivia Wilde, take a deep breath: You’re either on our Best or Worst Dressed list for this year’s Do Something! Awards. With that in mind, we’d like to pass along our fond “Congratulations! or sincere “Better luck next time!” to all of our finalists.

Dozens of celebrities, including Justin Bieber, Kim Kardashian, Victoria Justice and Adam Lambert, gathered in Los Angeles on Sunday night for the annual Do Something! Awards, an event in which they were able to honor their peers and some of the most devoted young people in the country committed to social change.

The award show, hosted by Jane Lynch and featuring musical performances from Demi Lovato, Foster The People and OneRepublic featuring B.o.B, is taping tonight at the Hollywood Palladium, but will air on VH1 this Thursday, August 18 at 9 p.m. ET/PT. However, you don’t have to wait that long to catch a glimpse of all the celebs in attendance who walked the blue carpet tonight —and a few shots of rehearsals, too!— in our gallery below.

If you don’t have a teen or tween living in your household, chances are you’re not familiar with Victoria Justiceyet. The 18 year-old is the latest in a long line of multi-hyphenates to emerge from Nickelodeon universe, thanks to her acting work on the sitcom that bears her name, Victorious, as well as her burgeoning music career. Her perky pop song, “Best Friend’s Brother,” has been bubbling up in the Billboard Hot 100 and iTunes charts for most of the summer, and now her cover of The Jackson 5 classic “I Want You Back” seems poised to make an appearance on more than a few playlists on the iPods of the millenial set. The cover was the focal point of this past weekend’s one-hour movie special, Victorious: Locked Up (hence the orange jumpsuits in the video), and the Victorious soundtrack hits stores today.
