Tonight (Feb. 10) in Los Angeles, stars gathered at the Staples Center for the 2013 Grammy Awards. As you can see from these performance pictures and show pictures from the 2013 Grammys, it was a night of mingling, laughs, remembrance and of course, great, great music.

Taylor Swift kicked off the show with a circus-inspired performance of 'We Are Never Ever Getting Back Together,' putting on a 4-minute spectacle so big we could hardly keep up with it. Towards the beginning of the 2013 Grammys, we also caught glimpses of newly reunited couple Chris Brown and Rihanna cuddling up in the audience, just four years after Brown's infamous pre-Grammy assault on the singer.

Chris and Ri weren't the only audience members buzzing with upbeat energy though. Photogs captured pictures of Beyonce laughing it up with newlyweds Justin Timberlake and Jessica Biel, and Ellen Degeneres appearing floored by her buddy Katy Perry's crazy cleavage. That John Mayer is a lucky guy!

Check out these 2013 Grammy performance and show pictures to get up close and personal glimpses of the action at the Staples Center.
