Rumor has it that Rihanna is the cause of Jay-Z and Beyonce's failed marriage. According to Page Six:

The source says the elevator fight after the Met Ball was really over Jay’s protégé Rihanna, whom 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.”

You've got to give it to Jay-Z. When he cheats, he really makes it count.

Jay-Z is apparently one controlling guy:

“There’s no bigger controller than Jay. She’s great, but she’d be a little lower on the totem pole if it weren’t for hooking up with him. In terms of ambition, talent, business acumen and work ethic, Beyoncé and Jay Z were perfectly matched. They are solid, solid business people who know what they’re doing.”

The source said that Rihanna is the real reason why Solange issued a camel beat down on Jay-Z.
