Watch extra 3-minutes footage of Jay Z/Solange fight released

TMZ obtained an extended version of the elevator footage which shows Solange continuing her attack on Jay Z for 2 more minutes.
I really do not think she will just attack Jay Z without reason , her action was erratic but not without reasoning . Saying she has Bipolar ( which has been Solange's guarded secret for a while ) is not a good enough reason to attack her elder sister's Hubby. something must have trigered it. And Beyonce didn't even blink move an inch , talk less of stopping her .  Watch the extended version above.
