The twerking isn't over yet…
A source confirms to E! News that the two have recorded the song together, which also features Bieber's pal Lil Twist. The up-tempo track is produced by Meajor Ali and hasn't officially been released yet, and there has been no word on whether or not this is the final version of the song.
Miley is heard belting, "I came up in the party, time to twerk," while the Biebs chimes in with, "Lemme see you get out on the floor, girl. We gonna party ‘til it's over."
"We can take it slow, don't need nobody to know," he adds.
The title of the soon-to-be hit track is surely timely. Just today it was announced that the dance term was officially added to the Oxford dictionary.
Given that the former Disney darling twerked for the world in everything from a unicorn onesie to flesh-colored, latex lingerie at the 2013 MTV VMAs, it seems like she should be part of the definition.
But, alas, she is not. According to Oxford Dictionaries, the term twerking originated in the '90s aka back when a pre-twerk Miley was just a little girl growing up in Tennessee.
The "informal" verb is defined as "[dancing] to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance." (Way to make it super technical, linguists.)
Oxford Dictionaries' Katherine Connor Martin said, per ABC News, twerking is most likely "an alteration of work, because that word has a history of being used in similar ways, with dancers being encouraged to 'work it.'"
"The 't' could be a result," she added, "of blending with another word such as twist or twitch." Terrific!
