Rihanna Stealing Jay Z from Beyonce?

According to mediatakeout.com, SOS singer Rihanna, wants to be Beyonce in every way. The pope babe has glammed so much to look like Beyonce that she is reportedly getting glances from Beyonce's longtime boyfriend Jay-Z.

Rihanna is becoming uncomfortably close to her mentor Jay Z writes mediatakeout.com. And that closeness reportedly bothers Jay Z's longtime girlfriend Beyonce. As one entertainment insider tells them, "Rihanna is desperately trying to steal Beyonce's look, her style, and even her sound ... I wouldn't be surprised if now she's trying to steal Beyonce's man."

At a recent NJ Nets game, Beyonce's frustration boiled over. According to a fan (SURE, I TOTALLY BELIEVE THIS) seated near the couple, Beyonce lost her cool when Jay Z received a 15 minute telephone call from Rihanna. Beyonce reportedly yelled out "why do you keep talking to her" and stormed out of the arena before Jay Z had a chance to explain.

Last month, while Beyonce was in Los Angeles accepting a star on Hollywood's Walk of Fame, Jay Z was reportedly in New York City wining and dining Rihanna.

Adding more fuel to the flame, last week Sources say Beyoncé had a roiling blowup with Jay-Z as New Jersey dribbled over Miami, 100-88 reports PageSix. "She stormed off and flew back home," one tipster said. Beyoncé's East and West Coast publicists were unaware of any fireworks. "I don't know if she had a fight," says Columbia Records' Yvette Noel-Schure.
