Chris Brown and Karrueche Tran Argue on Instagram

The saga of Chris and Karrueche seems to never end.

After breaking up for the umpteenth time, Chris Brown and his on-again off-again girlfriend, Karrueche Tran, exchanged choice words on Instagram today and this time, they held nothing back.

Karrueche exposed Chris's efforts to win her back and told him to "man the fuck up."

First off @chrisbrownofficial you just did an interview w Ryan Seacrest in which you spoke about me. My interview w Access Hollywood was not entirely about you.. they asked a question and as a mature adult I answered. I'm not gonna shy away from something that I lived through. I'm talking about my life and experiences. I'm not speaking on you or bashing you (like I easily could). Don't be mad at me because our relationship is over due to your lack of loyalty. You know what's weak?? You forcing yourself into my car.. my broken window.. blowing up my phone.. trying to shower me w gifts.. Man the fuck up and change the bs in your life like I've told you several times. Since you want to hear about my career - check out @vanityseries every Thursday on StyleHaul.com.. Emmy winning @thebaytheseries this Sept and 3 Headed Shark Attack on SyFy next month. Best of luck to you and beautiful Royalty ❤️

Breezy, who usually speaks without thinking first, had a surprisingly diplomatic response to Karrueche's rant, saying he is "eternally thankful" for their time spent as a happy couple.

I'm eternally thankful for you being in a part of my life. I've learned so much from you. I wish u nothing but happiness and the best. ❤️ @karrueche all I was doing was trying to fight for the woman I love. ThanxI learned a lot ✌️

Chris and Karrueche started dating off and on in 2012 and have had many public falling outs in the past. As Karrueche revealed during her recent interviews, the reason for their most recent break up was Chris Brown having a baby with another woman and keeping it from her.
