Earlier today footage from the Met Gala after party emerged showing Solange Knowles launching a vicious attack on brother-in-law Jay Z.
TMZ have released extended CCTV footage of the incident, which is over three minutes long.
Beyoncé, Jay Z and Solange can be seen entering a lift before the 27-year-old ‘
Sandcastle Disco’ singer hits out at Jay Z.
The video has caused quite a storm online and
old posts uploaded by the sisters have begun to resurface, one of which included a fairly interesting post uploaded by Beyoncé the day after the events occurred.
