Twerkin' Overtime.

Welp: That Lil Twist, Justin Bieber and Miley Cyrus Twerk Collaboration Finally Leaked.

At this point, you should be at least vaguely familiar with Lil Twist, the 20-year-old, Young Money-signed Oak Cliff rapper born Christopher Moore — if only for the fact that he's become a tabloid mainstay as the bad-influence scapegoat in the continued corruption of one Justin Bieber.

Now, though, you have another reason to know him: Today, the long-teased collaboration between longtime pals Bieber and Twist finally leaked. And, given that the track, which is set to come as part of Twist's also long-gestating debut LP, Bad Decisions, is called “Twerk,” you might not be surprised to hear that one Miley Cyrus also appears on the cut, singing the hook.

Sigh. This is America in 2013.
