What Was Miley Cyrus Doing at a Naughty Nightclub?

Miley Cyrus is only 17, but she partied last night at Voyeur nightclub, an adult venue that features topless dancers and S&M performances.

Miley hit the West Hollywood hot spot—sans Liam Hemsworth—to attend a private birthday bash. And by the looks of her short shorts and bare midriff, she seemed to be in the mood to show some skin herself.

So what was Miss Miley doing inside?

Keep your shirts on! Nothing too scandalous, according to sources at the scene.

“She wasn’t drinking, just dancing with a girlfriend,” one tells me.

Another partygoer, sitting at the table next to the teen, dishes: “I was expecting her to be pretty wild, but in all honesty, she seemed pretty chill and looked like she was having a good clean time.”

Miley’s rep didn’t respond to our request for comment.

The “Party in the USA” singer left Voyeur around 1:30 a.m., but didn’t want to get photographed. Her friends shielded her as she walked out, and then she hid on the floor of a pal’s car as they drove off.

Just another Thursday night in Mileyland, right?
