Oh boy.

Tiny troublemaker Lil Twist is teaming up with his pal Justin Bieber and Miley Cyrus for a new single, which much to Cyrus' delight, will be called 'Twerk.' (We're keeping an eye out for horsemen.)

Details about the song are scant, but it does help to explain why Bieber and Cyrus -- who've been longtime pals -- have been hanging out more often. It also ties right into Cyrus' sudden "urban" reincarnation. (A still from her infamous twerking video is used for the album art!)

So far all info has been from Lil Twist's Twitter. Apparently his first single from his upcoming record was due June 30, but got pushed back, possibly to make room for features from his fellow marijuana enthusiasts.

He also posted a tweet that implies both he and Cyrus may appear on Bieber's 'Heartbreaker' as well, writing:

Beliebers, Smilers and Team Twist -- are you excited or what?!
