Lil Twist's 'Twerk' Started As A Justin Bieber/Miley Cyrus Duet

'When it started off, it was Justin's record,' Twist tells MTV News of his collaboration with Bieber and Miley Cyrus.

Lil Twist's "Twerk" record may have seemed to come out of nowhere when it hit the Internet last week, but it sure came right on time.

The Young Money rapper says he doesn't know how his collaboration with Justin Bieber and Miley Cyrus leaked on August 28, just three days after Miley shocked music fans with her twerk-tastic, booty-shaking performance at the 2013 Video Music Awards.

"When it started off, it was Justin's record," Twist confirmed to MTV News during a sit-down in Los Angeles on Friday.

According to the Young Money rapper, "Twerk" was originally intended to be a part of JB's "music journal," a vague hashtag that the singer first used in April to tease a new project. His manager Scooter Braun told MTV News that Justin was writing up to two songs a day during his Believe tour, and he's been labeling them by the city he writes them in.

No telling which city he wrote "Twerk" in, but after a conversation over dinner at the popular Japanese restaurant Nobu, Bieber decided that the song would be better served in the hands of his friend. "He was doing 'Twerk' for 'Journals' with him and Miley and then once me and him had a conversation over dinner it was like, 'Yo bro, I think this should be your single and we should go with it'," Twist explained.

The record is produced by Maejor Ali and Chef Tone and features a catchy chorus from Cyrus, which only enhances Twist and Bieber's hyped-up performances. "I came up in this party time to twerk/ I came up in this party and I'm turnt," Miley sings.

The version of the song that is currently online is unauthorized, but that hasn't stopped fans from foaming at the mouth for the new party tune. It all falls in line with the world's newfound obsession with the dance that made mouths drop during Cyrus' August 25 performance. In an exclusive clip from an upcoming documentary about the singer, Cyrus says, "Me and Robin, the whole time said, 'You know we're about to make history right now.' "
