Jay Z and Solange's Met Gala lift row was over Rihanna, claims explosive unauthorised Beyonce book

Was Rihanna the cause of the row?

A new unauthorised Beyonce biography claims to know the real reason behind Solange and Jay Z’s infamous lift bust-up.
Celebrity journalist J. Randy Taraborrelli has written about Beyonce and Jay Z's marriage in the unauthorised biography, Becoming Beyonce, and alleges Solange attacked Jay Z because he wanted to party with Rihanna.
Taraborrelli sensationally claims Jay Z and Beyonce went on a secret break after Beyonce’s fierce work determination “drove a wedge” between them, three years before they wed.
It was during their time apart that Jay allegedly hooked up with his protege Rihanna, who was 17 and signed to his label Def Jam.

Beyonce and Jay Z are now happier than ever

A former member of Rihanna’s camp allegedly confessed to Taraborrelli that he made up the claims in order to kick-start the Barbadian beauty's career as a pop star.
They may not have hooked up but the author claims Beyonce believed the gossip and ended up having trust issues when it came to Jay.
Fast forward to last year’s Met Gala where Solange launched herself at Jay Z while they were leaving the annual event.

Jay Taraborrelli alleges the reason behind the bust-up was because Jay Z wanted to party with Rihanna and Beyonce said no.
“Why can’t you go home?” Solange is reported to have said, according to the New York Daily News.
That prompted the rapper to tell her to mind her own business, according to Taraborrelli, and everyone know what happened next...
