MILEY CYRUS stunned fans at a concert in Los Angeles on Saturday (08Dec12) by cavorting onstage with a topless stripper during a raunchy routine.

The 20-year-old former Hannah Montana star was a special guest at dub step DJ Borgore's Christmas Creampies gig at the Music Box, and turned up in a cleavage-baring crop top, skin-tight trousers and thigh-high animal-print boots.

The Can't Be Tamed singer performed Decisions, her new collaboration with Borgore, and was seen strutting alongside an exotic dancer, who wore just a thong and nipple covers as she swung on a stripper pole.

Speaking to Rolling Stone magazine backstage, Israeli producer Borgore admitted he was thrilled to have Cyrus join him for the sold-out show.

He explained, "We wanted it to be special. I really wanted her here, really. I feel like the second I go on the mic and there's another person on the mic, it goes extremely well. The kids in the electronic area don't get to see this s**t anymore, all they get to see is just DJs raising their hands up, being DJs. And putting more of a live feel to a show, two people on the mic singing, it just feels great... I'm really excited about this."

In their party-themed video for Decisions, Cyrus showed she is all grown up by cavorting with porn stars, tongue-kissing a pantomime horse and getting cake smeared all over her.
