Elevator fight : Solange went beserk on Jay Z because of Rihanna?

Here's what the New york post wrote ;

Over the past few months, says the source, Beyoncé has been losing respect for Jay Z and, ever on-brand, she’s been dropping hints.
While performing “Resentment” during the couple’s June 28 show in Cincinnati, Beyoncé changed the lyrics from “Been ridin’ with you for six years” to “Been ridin’ with you for 12 years.” That would reference the year they became a couple.

And after the lyric “I gotta look at her in her eyes and see she’s had half of me,” Beyoncé tacked on the lines, “She ain’t even half of me/That b*** will never be.”

The source says the elevator fight after the Met Ball was really over Jay’s protégé Rihanna, who he allegedly planned to meet later that night at his 40/40 club.

“Solange was like, ‘Enough is enough — you must be [screwing] Rihanna,’” says the source. “To many people who know them, they know it’s not out of the realm of possibility.”

Rihanna strikes again!
