My, my, my… what the hell happened here? A surveillance video has surfaced showing Beyonce’s younger sister attacking her brother-in-law, although it’s unclear what caused the altercation. Jay Z and sister-in-law Solange Knowles had an altercation at a Met Gala after-party May 5 that was caught on tape, obtained by TMZ.com.

It all went down in an elevator where the 27-year-old sister of Beyonce can be seen clawing and kicking at her brother-in-law as the “Halo” singer looks on. It’s unclear what caused the argument as there is no sound on the black and white surveillance video, shot after the group attended a soiree at the Boom Boom Room at New York’s Standard Hotel.

As they walked into the elevator where Beyonce already stood, Solange appeared to immediately begin screaming and pointing in Jay Z’s face.

While it seems he had some words of his own, when Solange began attacking him, Jay Z looked like he was trying to hold her arms down as another unknown man, presumably a bodyguard, held her back.
It appears the bodyguard attempted to keep the altercation private by pressing the emergency stop button on the 12th floor repeatedly.

Beyonce initially remained calm and leaned against the elevator wall. She finally appeared to say something to Solange after she broke free and approached Jay Z again, kicking and punching.
Solange walked ahead of the couple as they exited the elevator and did not look happy. Jay Z strolled behind his wife.
