People I'd be okay with Nicki collabing with for The Pinkprint:
Kanye
Jay-Z
Beyonce
Eminem
Big Sean
J Cole
T.I.
B.o.B
Iggy Azalea
Taylor Swift / Justin Beiber
She should collab with maybe five of those people for her next album. The guys are all amazing rappers, a Beyonce song would be MAJOR, an Iggy collab would prove she supports up and coming female rappers, and a TSwift/Beibs collab would get those fool tweens on her side.
