Jay-Z is definitely a business, man. He has managed to expand his RocNation Management business by signing the hottest female artist around…no not Taylor Swift…Rihanna. RiRi told the Associated Press in an official statement that she’s “excited to take the next step in my career.” As part of the deal, Rihanna will also be launching her own business group called Rihanna Entertainment which she states will “merge all of her businesses, including music, film, fragrance fashion and book ventures.” It should have been called RiRi Entertainment, or at least EyEy Entertainment or something a bit more…creative? Regardless, Jay and Rihanna about to take over the urban entertainment world.
