Honestly, I thought she was already on Roc Nation but allegedly the lovely bad girl Rihanna has left Def Jam and has officially signed on to Jay Z's record label, Roc Nation. Jigga signed her when he was President of Def Jam back in 2005. Even after Jay left Def Jam to start Roc Nation, she stayed on board at Def Jam but she did remain to be managed by Roc Nation since 2010. 

After all of the confusion and staffing changes at Def Jam, Rihanna has decided to go all the way with Roc Nation. Honestly, nothing is going to change probably musically or image wise.
