Rihanna and Jay-Z accused of having secret affair behind Beyoncé's back

Cheating allegations said to be behind rumoured marriage breakdown and the reason why Solange Knowles attacked the rapper in a lift at the Met Ball

BEYONCÉ and Jay-Z's marriage has been under fire for months.

The rapper has been accused of cheating and the pop star is believed to be on the verge of leaving him after 12 years together.

Now, Rihanna has been brought into the mix as rumours reach an all-time high.

According to the Mirror, the Monster singer is Jay-Z's other woman.

The alleged affair has been going on for a long time time and is supposedly even the reason why Beyoncé's sister Solange attacked her brother-in-law in a lift at the Met Ball earlier this year.
