In a shocking video obtained by TMZ, Solange attacks her sister's husband in an elevator at the Standard Hotel, where they were at an after party.
It's unclear what caused the altercation, but you can see Solange begin flipping out and getting in Jay's face as soon as they enter the elevator. She manages to hit him a few times before being restrained by a man who appears to be one of their security guys.
Even while being held back, the 27-year-old continues to lash out at the rapper and starts kicking him. You can see Jay grab her foot to defend himself, but he never attempts to hit back at her. In the meantime, Beyonce just stands in the corner calmly doing nothing, which is pretty crazy.
But the footage of the trio exiting could provide an important clue to what side Bey's on. The "Drunk in Love" singer gets into a car with her sister, while Jay leaves in another vehicle solo. She also Instagrammed a photo of a prayer on Wednesday, asking for "strength to separate myself from anyone who is not a good influence."
There's been no official comment yet from Bey, Jay or Solange, but we're dying to know what caused this awful incident. Stay tuned.
