After last week's Met Gala in NYC, Jay Z, Beyoncé, and her sister Solange were at an after-party at the Standard Hotel. According to TMZ, Solange allegedly physically lashed out at Jay inside of an elevator, and the action was caught on a surveillance camera. The report alleges that Solange "ferociously assaulted" him, "wildly kicking and swinging." Update: TMZ has posted video of the full, 3-and-a-half minute elevator ride, showing an even longer attack.

Per TMZ, "A large man—who appears to be a bodyguard—attempts to hold Solange back, but she manages to connect at least three times... Solange throws a kick and Jay grabs her foot, but never attempts to strike her. Beyoncé stands by without getting physically involved."

TMZ posted the surveillance camera video:
