According to All Hip Hop, singer Rihanna may have chunked the deuces to Def Jam and signed with her mentor Jay Z's Roc Nation label, where she is also been managed for quite some time.

On Def Jam’s official site, Rihanna is not listed in the ARTIST section with such current artists as Kanye West, Frank Ocean and former rival Teyana Taylor. Rihanna enlisted Jay Z’s Roc Nation as help with her management in 2010, however the site now has Rihanna as a LABEL artist along with J. Cole, Jay Electroinca and others: -- All Hip Hop.com
