Rumors of a divorce have been following hip hop couple Beyoncé and Jay Z for a long time now, and now a new name has been linked into the mess, none other than Barbadian singer Rihanna, Celeb Dirty Laundry reported.

The couple allegedly had a heated argument over Jay Z cheating on Beyoncé with younger pop singers, with some reports even calling out Rita Ora as one of Jay Z's supposed ladies on the side. However, this recent argument in particular focused on only one singer, Rihanna.

In fact, an eyewitness who caught the Beyoncé and Jay Z showdown told Naughty Gossip it occurred in public at a sushi restaurant in Los Angeles.

The source said, "She was screaming at Jay Z in front of everyone. Beyoncé said, 'that b*tch Rihanna' during her tirade. He kept saying sorry, but she was having none of it." The source even added that Beyoncé "won" the argument.

The source's claims certainly seemed related to the photos that have appeared online on websites such as Radar and Hollywood Life.

A few photos were taken by eyewitnesses and were posted online showing the couple at the supposed sushi restaurant in L.A. arguing over dinner. Beyoncé could be seen looking angry lashing out at her husband, even pointing a finger at him as she talked. Looking at the photos, Jay Z could be seen keeping silent while Beyoncé talked on.

There were even other photos that showed Jay Z looking at his phone and Beyoncé not looking so pleased to see she was being ignored.

Their public argument also seemed to support the insider information a source shared to Radar saying that behind closed doors, Beyoncé and Jay Z "are not as happy as people think they are."

It follows a slew of other news, rumors and messes that have been popping up about the couple's relationship, beginning with the incident several months ago when Beyoncé's sister Solange was caught on camera hitting Jay Z while they were in an elevator. Some said that Solange was defending her sister after seeing Jay Z flirt with another woman, according to CelebDirtyLaundry.

Their "On The Run" Tour, which was held last year, was also rife with rumors and reports that Jay Z was cheating on his wife and partying.

The couple has neither confirmed nor addressed the rumors, usually ignoring them. So until they both talk about it, nobody actually really knows how Mr. and Mrs. Carter's relationship is going.

A recent report does seem to work in their favor though as TMZ reported that the couple has decided to move to Los Angeles. They recently enrolled their daughter Blue Ivy in school and a source close to the couple even claimed that they wanted "a change in lifestyle."

One can only wonder if their decision to move houses also had something to do with their supposedly struggling marriage.
