AMAs 2011: Taylor Swift, Nicki Minaj Win Big on Ladies' Night

Photos of the Year 2011

November 20: Selena Gomez, Nicki Minaj, Katy Perry and Taylor Swift in the audience at the 2011 American Music Awards in Los Angeles.

Kelly Clarkson, looking ready for the holiday season in a sparkling red floor-length dress, took the stage for her performance of "Mr. Know It All" with a "Newsies"-style open that poked fun at her label dramas and rumors about her sexuality.

And Adam Lambert's return to the AMAs stage -- the first since his controversial performance in 2009 -- was greeted with some of the night's biggest applause as he introduced OneRepublic.

"Wow, has it really been two years?" Lambert said.

Before the ceremony, Hot Chelle Rae, who won Sprint New Artist of the Year, wowed the red carpet crowd with performances of "Tonight Tonight" and "I Like It Like That" during the pre-show. Taio Cruz and Marianas Trench also performed.

A handful of awards were announced off-camera, including Favorite Pop/Rock Female Artist (Adele) and Favorite Soul/R&B Male Artist ( Usher).

The night ended with a predictably silly performance by party rappers LMFAO, who did a medly of recent hits complete with goofy cameos by Justin Bieber, David Hasselhoff and YouTube star Keenan Cahill.
