Is it bad that we kind of love it?!

Miley Cyrus and Justin Bieber have collaborated on a new song that was leaked today called "Twerk", and the name of the tune speaks for itself!

The "We Can't Stop" singer is famous for the bootyshaking dance after her disastrous performance at last Sunday's VMA's, and although you would think she would try to distance herself from associations with the dance fad after all the bad press, apparently the song was recorded a while back.

JB's pal Lil' Twist is also featured on the single.

We wonder if The Biebs wishes he could take this back?
