Rihanna and her ex-accountant are BEFFIN’ and the money man is now firing back in their legal battle over $9 million RiRi claims she lost while he was her accountant. He now is calling her a financially impaired moron. Accountant Peter Gounis filed the response to Rihanna’s lawsuit claims he was hired to record and manage her financial accounts. He was NOT hired for watching her shopping sprees. He admits that Rihanna SPENT millions of her own money by going on endless shopping sprees — buying roomfuls of designer shoes, clothes, and jewelry — and throwing extravagant parties for herself. He then adds she bailed on an expensive tour to shoot “Battleship,” which turned out to be a horrible idea. Gounis says, “Was it really necessary to tell her that if you spend money for things you will end up with the things, and not the money?” Gounis wants Rihanna’s lawsuit deaded!
