What the twerk!? Miley Cyrus and Justin Bieber apparently have a new song coming out that's all about twerking. Three days after Cyrus' controversial MTV Video Music Awards performance, a track titled "Twerk" was leaked online Wednesday, Aug. 28.

The song features Cyrus, 20, Bieber 19, and rapper Lil Twist, 20. In the chorus, the former Hannah Montana star sings, "I came up in this party time to twerk." Back in July, Lil Twist announced the group's collaboration by tweeting the cover art for the single. The image shows Cyrus twerking in a unicorn onesie from her dance video that went viral in March.

The release of the track -- though apparently leaked -- couldn't have come at a better time. Cyrus made twerking center stage at the VMAs on Sunday, Aug. 25 during her raunchy performance of "We Can't Stop" and "Blurred Lines" with Robin Thicke.

According to Quartz, the word "twerk" has even been added to the Oxford Dictionaries Online. "Twerk" has been defined as "a dance to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance." Bieber and Lil Twist aren't Cyrus' only high-profile collaborators, either: Kanye West is also teaming up with the young singer. A source told Us Weekly that the two skipped the post-MTV VMAs festivities to lay down a remix of the 36-year-old rapper's "Black Skinhead."
