Perhaps there’s a bit of a family feud going on in the Carter household.

TMZ has obtained raw video of from New York’s Standard Hotel which shows Solange Knowles, the younger sister of Beyonce, attacking Hov on an elevator during last week’s Met Gala.

A large man — who appears to be a bodyguard — attempts to hold Solange back, but she manages to connect at least 3 times. At one point Solange throws a kick and Jay grabs her foot, but never attempts to strike her. Beyonce stands by without getting physically involved.

It’s unclear what triggered the fight.

And this is interesting. When you look closely, you see the bodyguard hit the emergency stop switch on the 12th floor — mid fight — presumably to keep the fight private.

This photo was taken as they left the party … and Solange looks pissed.

Maybe Solange is pissed that she’s not the opening act for the On the Run Tour. Either way, Hov needs to get his extended family in order.
