Jay-Z's slow and deliberate attempt to take over every former artist he had on Def Jam on his new Roc Nation continues with the news that Rihanna has signed with Jay's Roc Nation Management, the management arm of Jigga's new empire. As part of the deal, Rihanna gets her own company, Rihanna Entertainment. She isn't technically on Roc Nation the label yet--she's still signed to Def Jam--but I can't imagine she'll be staying past her current contract. [AP]
