Justin Bieber is certainly stepping up his rap game. After dropping a few freestyles the past year—such as "Otis"—on radio and on Ustream, the 18-year-old pop prince is rapping all over his new single, "Boyfriend."

And while the Ying-Yang twins added their own raps to the song to make for an unofficial remix, The Biebs has plenty of sanctioned hip-hop collaborations for his June 19 LP, Believe. Today, Island/Def Jam released the tracklisting for Bieber's album and a handful of your favorite rappers are down with the Canadian sensation.

Ludacris appears on the track, “All Around The World,” which opens up the album, while Big Sean checks in on a record titled “As Long As You Love Me.” Not to be outdone, Bieber calls on Young Money champions Nicki Minaj and Drake to round out his guest spots. Nicki is featured on "Beauty And A Beat" and one can find Drizzy on "Right Here."

A few weeks ago, photos of Bieber and Kanye West in the studio surfaced, but there has not been a definitive word of what that session has spawned and where a song or songs between the two will surface. Island Def Jam has listed Max Martin, Mike Posner, MdL, Diplo, Hit-Boy, The Messengers, Zedd, and Rodney Jerkins as producers on the new album.
