Beyonce and Jay Z fighting over his secret phone to call Rihanna?

Sources claim Beyonce is livid that Jay Z has a secret phone to call Rihanna for their business calls From The Mirror Beyonce is reportedly fuming at Jay-Z for having a secret phone to call his protégée Rihanna. Beyonce is said to have been rowing with her husband over the singer after she discovered the mobile which is reportedly for business purposes. A source told Grazia magazine: "Jay has several phones, one of which he keeps reserved for Rihanna, supposedly to discuss business interests. "It's obvious when she calls because he'll interrupt meetings, even walk away from the dinner table to speak to her." The insider claims Beyonce, 33, knew Jay had a number of phones but wasn't aware RiRi had a hotline to her husband and hates how close they are. Jay has vehemently denied that him and Rihanna have ever been more than friends and work colleagues after rumours went into overdrive last May.
