It seems hard to believe that Rihanna could have already recorded a new album, but that might be the case. The French branch of her record label, Def Jam, recently tweeted that the singer will drop a new album in November, with a single coming as soon as Monday. However, that tweet has since been deleted and the label tweeted out a new message stating that a Rihanna announcement would be made today. A rep for the singer confirmed to MTV News that Rihanna does have a new album coming out, but didn't provide any further details. Meanwhile, the singer recently announced her 2013 Diamonds World Tour, which will kick off in March.
