One of the best parts of the 2013 American Music Awards was seeing our favorite stars -- all mingling together! Thanks to Twitter and Instagram, we're able to see who was hanging out tonight.

Emma Roberts (with Liam Payne from One Direction) said 1D is her favorite band.

Naya Rivera (and her display of sideboob) hung out with Jordin Sparks and Lance Bass.

Miley Cyrus celebrated her 21st birthday again, backstage with Kelly Osbourne.

"Best seat in the house at the #AMAs." -- R.Kelly

Kesha and Kelly Osbourne in an elevator. Totally normal.

So much star power!
