Eminem has broken his silence on the highly-anticipated Relapse 2 album and said fans should expect to hear 50 Cent on the project along with production from Just Blaze.

While not naming any song titles, Slim Shady said his collaboration with the G-Unit leader features them exchanging eight bars.

"Me and Fif did a couple of records, couple of months ago in Vegas, one song for my record and another for his," Em revealed in an interview. "We just wanted to like, I just had an idea to like 'Yo, why don't we do something we ain't done yet.' And kinda go back and forth, we've kinda done it on other records but not to the extent of what we're doing on this one...The way that it's going now"

"K'Naan has two [produced] tracks on the record and Just Blaze has four, possibly five...I definitely feel like I'm in a little different space right now," Em added.

No release date for Relapse 2 has been revealed.
