Rihanna revealed as the reason for Solange’s elevator frenzy

The mystery surrounding that infamous elevator attack just keeps on getting juicier.

And now the finger has been pointed at Jay Z’s pop protégé Rihanna as the reason Solange lashed out at her brother-in-law after the Met Ball last week.

Solange is said to have gone beserk on Jay Z after the rapper said he was attending Rihanna’s Met Ball after-party without his wife.

The blazing row was apparently sparked by Jay-Z, who snapped at Solange when two of her friends tried to use his name to get into the post-gala soiree at The Standard hotel.

And it was when Solange demanded they leave the bash, that Jay Z said he was heading off to Rihanna’s party without Beyoncé – which did NOT go down well with her little sister.

Solange is said to have been more than a little suspicious that Jay Z wanted to go to Rihanna’s bash alone, and demanded that he stay with his wife instead of going out partying.

Jay Z didn’t back down, and apparently accused Solange of being a ‘bad mum’ for going out all the time herself.

Oh no, he didn’t!!

This really isn’t going away any time soon!
