Pals Miley Cyrus and Justin Bieber have collaborated on a leaked new song, titled Twerk.

The song hit the airwaves on Wednesday (28Aug13), just three days after Cyrus hit headlines for her sexually provocative performance with Robin Thicke at the MTV Video Music Awards on Sunday (25Aug13), during which she gyrated and 'twerked' onstage with the 36 year old and at one point thrust her backside into the hitmaker's crotch.

In the new track, Cyrus and Bieber sing about approaching girls in a club.

She sings, "I came up in the party, time to twerk/I came up in the party and I’m turnt (sic)."

The track was orchestrated by Bieber's friend Lil Twist.

Bieber isn't the only superstar Cyrus has recently collaborated with, she has also reportedly teamed up with Kanye West for a remix of his song Black Skinhead.
