Chris Brown just went all the way OFF on Instagram after Soulja tweeted that he chilled with his daughter's mother, Nia Guzman, and his daughter, Royalty Brown, while at Floyd Mayweather's house.
"Stop talking about my daughter" Chris warns Soulja in the profanity laced below which he captioned:
"IM NOT PLAYING! Krossed da line...... We gone push this fight UP!!! I promise you are regret this for the rest of ya life."
