Miley Cyrus Parties With Tyler, Wiz And Amber For Her Birthday: See Their Pics

After singing 'Wrecking Ball' at the American Music Awards, Miley turned up the fun with a post-awards birthday bash.

What’s a girl to do after she closes out a major award show? Well, if you’re Miley Cyrus, you party.

After Sunday’s catty American Music Awards performance of “Wrecking Ball,” the now 21-year-old singer threw herself a little 21st birthday bash, letting loose with Tyler, The Creator, Wiz Khalifa and Amber Rose.

While Miley didn’t share any photos on her own account, her pals did. The party had a photo booth, balloons and giant cut-outs of Miley’s face — complete with her sticking out her tongue — that guests could pose with at the party.

“Faded #HappyBirthdayMiley!!!!! Had a blast at ur BDay Party tonight,” Amber shared after the fete. “Was lookin for ya drunk ass Lol U remind me so much of myself when I was 21. F— the world bitch ur the sh–! I got cha back babes through what eva. @mileycyrus”

In fact, before she even took the stage in Los Angeles, she was popping bottles and downing cupcakes. She hung out with pal Kelly Osbourne backstage at the AMAs where she rocked a birthday tiara.
