How shocking! 17-year-old Miley Cyrus attended a night club for over 21s.

“She was constantly smiling and seemed to be in great spirits,” an onlooker told UsMagazine.com.

Miley apparently “waved her hands in the air and danced seductively while shaking her hips” to songs by David Guetta and DJ Khaled.

Wearing a tiny black top and short-shorts, Miley was reportedly on her best behaviour throughout the evening.

“It was clear she knew she was being watched by others,” the source said, adding that Miley and her girlfriends were flanked by a security guard at all times. “No alcohol was in her presence the entire night.”

“Miley looked care-free and let loose with the girls,” the source told Us. “She looked happy and seemed to be taking advantage of her time out in the club.”

Miley called it a night at 1:30am.
