Really don't think this has anything to do with Beyoncé. Bey is not some 5 year old girl, she can speak for herself. I'm sure her and Jay have gotten into plenty of fights, non physical most likely.
It irks me that Bey never expresses what she's truly feeling. Maybe Solange took it upon herself to convey Bey's true feelings towards Jay? Maybe that's why Bey was so unfazed at her sister lashing out at her man.
Beyonce is such a non violent person. You can tell. There's no way in hell my sister would openly attack my husband like that, even if it were in my defense. I would have told her to sit her ass down in a corner somewhere.
You are not a child. Children get away with tantrums like this, not adults. I am deeply surprised there's not a mug shot of Solange floating around yet.
