Miley Cyrus hit the red carpet at the 2013 American Music Awards at the Nokia Theater in Los Angeles on Sunday night, and we were somewhat surprised to see the starlet wearing a pantsuit and minimal makeup! She looks great but she's toned down her look significantly since the MTV Video Music Awards...

Though Miley wasn't nominated for any trophies this year, she close the awards show with "Wrecking Ball," and while she showed a significant amount of skin, it was a pretty tame set for her! And honestly, who's looking at her two-piece kitten spandex getup when her voice sounds this amazing:

In other news, Miley turned 21 yesterday, but it looks like the party is still going! Her pal Kelly Osbourne posted the photos below and tweeted, "Celebrating @mileycyrus 21st birthday back stage at the #AMAS with @dendoll! Thank god she is finally legal!"
