Miley Cyrus still can't be tamed!

The 20-year-old put on quite a show Saturday during Israeli electronica DJ Borgore's "Christmas Creampies" concert at the Fonda Theatre in Hollywood. Appearing as a surprise guest performer, Liam Hemsworth's fiancée hit the stage after midnight and showed some serious skin while singing and dancing with a topless stripper.

For her performance, Cyrus emerged wearing body-hugging black stretch pants and a chest-exposing crop top that left little to the imagination. The former "Hannah Montana" star also had on a chain belt that doubled as a necklace and knee-high python boots.

What A Hot Mess!!!
