But now it appears that Rihanna has very quietly made another move. Within the past few weeks, her Roc Nation website profile has been updated to specify that she's not just managed but also officially signed to the label—joining the likes of Calvin Harris, DJ Mustard, J. Cole, Jay Electronica, Rita Ora, and of course, Jay Z. (Roc Nation management represents many other stars, including Beyoncé) Meanwhile, the Def Jam website now lists Rihanna under "Legacy" section, along with folks like Amerie, Ashanti, and Slick Rick.
This is major news—one of the world's biggest pop stars switching labels—but somehow the whole thing has been kept under wraps. Def Jam and Roc Nation have always had a very close working relationship, but the Rihanna signing is a game-changer for Roc Nation, as RiRi will become the label's biggest star—with the possible exception of Jay himself.
Rihanna's publicists at 42 West have yet to confirm, but we reached out to some well-placed sources who confirmed that Rihanna is now a Roc Nation artist—signed to both the label and the management company. Which makes sense—having fulfilled her Def Jam album contract, she's back with Hov at the Roc. The big question now is when can we expect Rihanna's first Roc Nation release? Only time will tell.
Even more creative control for the Queen of Pop
staying with those who helped make her who she is 
I wonder why, since everything has been going so well for her the way things were
