| by Kate Wharmby Seldman

Singer and actress Miley Cyrus celebrated her 18th birthday at the Hollywood club Trousdale on Monday night. She wore a revealing outfit of black leather pants, belly-baring black leather bra top and high-heeled boots.

Celebrating along with her were her mother Tish, Demi Moore, and her daughter Rumer Willis: Moore plays Miley's mom in the upcoming movie "LOL."

Also at the bar was Avan Jogia, Miley's latest boyfriend. He's a Canadian actor who's been in shows like the CW's "Aliens in America," and Nickelodeon's "Gym Teacher: The Movie" and "Spectacular."

Currently he stars in the Nickelodeon show "Victorious." He's also 18, which explains why it was OK with Tish Cyrus that he draped her daughter backwards over the bar and kissed/bit her neck. Check out the full-size photo:

Meanwhile, yet another Miley Cyrus wardrobe-malfunction picture is making the rounds. This one shows the young singer in a white bodysuit that's barely covering her undercarriage.
