Beyonce and Jay Z relationship is back in the limelight. And this time, some new claims have let old skeletons rolling out of the closet. According to latest reports, a new tell-all book has revealed the truth behind the powerful couple's relationship and has apparently thrown some light on the rapper's rumoured fling with Rihanna.

Well, we all know that the web is flooded with reports suggesting that rumours of an alleged affair with Rihanna have hovered Beyonce-Jay Z's marriage for years. But now, a brand new tell-all book claims that these rumours went so wild that it took a toll on their marriage. And that the blow was so big that they actually "secretly split for a year," reported OK! Magazine.

According to the report, J Randy Taraborrelli has written in his book "Becoming Beyoncé" that though Jay's rumoured fling with RiRi, who was just 17 and a rising star then, was just a story with no truth in it. But it did upset Bey, who couldn't take the reports as lightly as she should have.

"Beyoncé didn't know what to make of this, and it actually ended up breaking them up for a time. They spent maybe a year apart from each other because Beyoncé just wasn't sure of what to make of the situation with Rihanna," the book read.

The website also reported that the book pointed out that the affair rumours were in the air during the early stages of Rihanna's career, but Beyonce was mad about this for many years. And the books blames this to be the reason that caused the infamous elevator fight in 2014 with her sister, Solange.

"People told me that there was a whispered argument that night having to do with Jay wanting to go to a party for Rihanna. Beyoncé did what Beyoncé does. She laid down the law . . . it was a whispered married couple's argument that would've gone by completely unnoticed had not Solange overheard it," Randy wrote in the book.

Apparently, he also claims that these cheating rumours were initiated as a PR stunt to give the "Diamonds" singer's career a boost. And that Riri and Beyonce are good friends now.

Well, we don't know far this tell-all book is true. But what we know is that Beyonce and Jay Z are still considered to be a powerful couple in the industry.
