Rihanna has reportedly left Def Jam records and officially signed with Jay Z's recording label Roc Nation. Jay Z signed Rihanna to Def Jam back when he was president in 2005. Since then the superstar released seven albums under the label. Due to a lot of changes at Def Jam over the years RiRi felt it was time to jump ship and head over to Roc Nation officially.
According to HipHopWired.com :
A lot has changed at Def Jam...Former CEO Barry Weiss stepped down earlier this year, which led to corporate parent Universal Music Group dissolving the company into three separate record labels: Def Jam, Island, and Motown. The latter has ultimately resulted in Rihanna leaving to join Roc Nation, whose team has been managing her since October 2010. Riri's updated profile on RocNation.com indicates she's not only being managed by them, but fully housed. Though her publicist have yet to speak out, sources close to the singer confirmed that Rihanna is now a Roc Nation artist, signed to both the label and its management company.
