Karrueche Tran slammed Chris Brown over his recent interview with Ryan Seacrest where he said that he was trying to “fight for the woman he loves.” Tran wrote on her Instagram account on Sunday that her relationship with the singer ended because of his “lack of loyalty.”

Tran broke up with Brown in March after she discovered that he had fathered a child with model Nia Guzman. Since then, Brown has been making efforts to get back with her, but the 27-year-old has rejected his constant requests for reconciliation. In her latest post, Tran called Brown “weak” and asked him to “man 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,” Tran wrote in her post. “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.”

She also wrote about Brown’s behavior earlier this month, which forced police to pull up outside her residence late at night.

“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 f*** 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,” Tran wrote.

Brown’s attempted reunion with Tran, at the Playhouse Nightclub in Los Angeles on June 4, turned dramatic after the former forced himself into Tran’s SUV. Tran reportedly asked Brown to get out of the vehicle following which he showed up at her doorstep late that night and banged on her door forcing her neighbors to inform the police.

In a recent interview with Access Hollywood, Tran stated that she has no future with Brown and her daughter, Royalty. Just days after Tran’s interview, Brown told Seacrest that he still loves Tran but his main focus is his daughter. 

“No doubt his heart is broken. He’s finally on the opposite side and knows what it feels like to be hurt,” a source told Hollywood Life. “But there’s nothing he can do about it other than learn from his, and he’s doing that. He knows that he caused this by lying and cheating, and in actuality, he knows he doesn’t deserve Karrueche.”
