Beyonce's sister Solange Knowles allegedly attacked Jay-Z inside an elevator during an after-party following the Met Gala last week in New York City.
According to TMZ, the incident happened inside an elevator at the Standard Hotel soon after the party concluded.
After Jay Z, Beyonce and Solange stepped into the elevator, the fireworks began and were captured on a surveillance video (below).
Solange reportedly yelled at Jay-Z and then pushed and kicked him while he stood next to Beyonce.
At one point, Jay-Z grabbed Solange's foot, but never hit her back. Beyonce did not get involved in the fight.
Another man in the elevator tried to hold Solange back, but she appeared to kick Jay-Z yet again, noted Gawker.
Moments later, when Jay-Z, Beyonce and Solange exited the hotel, they acted completely normal (pictured), except Beyonce and Solange got into one car while Jay-Z appeared to be hunting for a ride.
“Solange doesn’t like the way Jay Z controls Beyonce," an unidentified source told HollywoodLife.com. "Beyonce would never speak up to him or defend herself, so Solange does it. Solange is not afraid of him and is fed up with him calling all the shots in Beyonce’s life."
“Solange doesn’t like that Jay Z is so controlling," added the source. "That’s why Beyonce didn’t do anything, because Solange was coming to her defense. Solange and Beyonce are extremely tight and Solange has always been very protective of her. Obviously Solange couldn’t take it anymore and flipped out."
