Miley Cyrus has been reunited with a stripper pole.

But this time — more than three years after Cyrus, then 16, straddled a stripper pole at the Teen Choice Awards — the controversial prop was accompanied by an actual, topless stripper.

As a guest performer at dub step star Borgore's "Christmas Creampies" Saturday Dec. 9 concert in Hollywood, the 20-year-old Hannah Montana star sang and strutted alongside a dancer (wearing just a thong and pasties) doing her thing.

Not that Liam Hemsworth's fiancee was modestly dressed herself. Sporting her now-familiar blonde, punk pixie 'do (recently buzzed at the sides) the "Can't Be Tamed" singer wore a tiny top with strategically placed cutout revealing her cleavage, a gold body chain, tight leather pants and knee-high leopard-print boots.

At another point in the performance, Cyrus appeared to nearly make out — or at least get very up-close-and-personal with — a male performer onstage.

Cyrus has collaborated with Israeli-born Borgore on his new single "Decisions" and appeared in the video with a porn star, Jessie Andrews.

As for her own ever-evolving sound, Cyrus' fourth studio album is out in 2013, and features collaborations with hip-hop mega-producer Pharrell Williams, rapper Mac Miller and others.

"I'm really proud of the album," Cyrus told Us Weekly earlier this year. "It's my favorite thing I've done probably ever," she gushed. "It's all really different."
