He shouldnt have done that. That was not very nice. If he didnt want her back there he could have told her to leave. Somebody had to invite her back there and for him to post this for the world to see was extremely disrespectful. He owes her an apology..idk about money..but definitely a public apology.
Now I realize why people hate 2chainz so much. This is a woman that 99.9% of brothers would have no chance in hell with, but 2chainz brushes her off like she not isht.
