Guess who's back? After a nine-year hiatus Mase (or is it Pastor Mase?), went on Twitter Friday night (Oct. 18) to announce that he's working on a new album.

The former Bad Boy rapper is calling his fourth studio album 'Now We Even' and is already plotting his dream collaborations for his new project.

The Harlem World rhymer posted a laundry list of artists he would love to collaborate with on his album, which included such A-Listers like Drake, Jay Z, 2 Chainz, Lauryn Hill, Meek Mill, Beyonce, and yes, even his former boss Diddy.

Only time will tell if Mase can get all those big-names on his album, but it shouldn't be an obstacle for him. The 'Feel So Good' rapper is even welcoming a reunion with fellow Harlem rhymer Cam'ron, which should be interesting if he manages to pull that one off.

Check out Mase's tweets below:

Welcome back, Mason Betha!
