Where do we sign up for Miley Cyrus's life? It's a non-stop Party in the USA. At only 19, she's filthy rich; successful across music, TV and film platforms; and engaged to hunky Hunger Games actor Liam Hemsworth. It's a good thing she's adorable — and the loving mama to rescue dogs — or we'd be so green with envy we'd Hulk out.

Miley seems to be a Saturday night fixture at Beacher's Madhouse at the Hollywood Roosevelt Hotel and this week People says she was back in the club with her girlfriends — once again minus her busy fiance, Liam, who has a half-dozen movies either filming right now or in pre-production.

"She was in her usual happy mood and was very social and upbeat," an onlooker told People. "She was very chatty with everyone at her table." Miley reportedly arrived just after midnight and started dancing to Flo Rida's "Whistle" and Chris Brown's "Turn Up the Music."

People says drag queen Vicky Fox was toasting people's birthdays and invited Miley to come up and sing her "Happy Birthday," so Miley got on stage and sang for everyone. The future Mrs. Hemsworth reportedly stayed until the club closed. She can't be tamed — and we love her for it!
