So someone has finally leaked some insider info on why Bey’s little sister went at Jay Z at the Met Gala. Even celebs are not immune to family issues.

Daily News has reported that it all started when some of Solange’s non-celeb friends arrived at the met Gala, throwing Jay’s name around and trying to get in on his merit, rather than claiming they were with Solange. This irritated him, apparently, and he made a sharp comment to Solange which ruffled her slightly boozed feathers. When her homies were not allowed in, Solange decided it was time to go home.

Tensions were already running high when Jay Z — while walking to the now-infamous Standard Hotel elevator — said he was going to the Rihanna bash rather than heading home with Beyoncé.

“Why can’t you go home?” a drunken Solange Knowles said to her brother-in-law as they left the swanky May 5 Met Gala after-party, a source told The News. Then the 27-year-old singer turned to her 32-year-old big sis Beyoncé.

“Why does your husband need to go to the club right now?” Solange asked, according to the source.

An incensed Jay Z took offense to Solange getting involved in his business. “You’re one to talk,” he shot back at Solange, the source said. Jay Z’s sharp reply sent Solange into a violent rage. She attacked Jay Z with a series of furious kicks and punches in a three-minute outburst that was caught on surveillance video and leaked Monday.

So there you have it. Of course there are still lots of guesses about family divisions and more dramatic problems, but that seems about right for a family of celebs. Ok, shows over, back to the real world.
