JAY-Z ATTACKED BY BEYONCE'S SISTER SOLANGE!!!!!

So this video went viral today and I must say I'm not surprised at all. Now something Jay-z said must have ticked Solange off because she had some words for him once they entered the elevator. Now the shocker to the video is Beyonce didn't react at all. I mean that altercation must have been very uncomfortable or very familiar. What do you guys think??? Take a look at the video and see for yourself.
