Beyonce's sister attacks Jay Z

  • TMZ obtained a nearly 4-minute-long elevator surveillance video, which shows Beyonce's sister Solange Knowles attacking Jay Z. 

    It appears that the attack took place at a hotel in New York and the video clearly shows Solange screaming at her brother-in-law as Beyonce stands by them without getting involved in the fight. 

    It hasn't become clear as to why the fight started, but Beyonce got in a separate car with her sister after the three of them left the hotel, according to media reports.
