Chris Brown reportedly dissed ex Rihanna to win back on-and-off girlfriend Karrueche Tran.

Hollywood Life previously reported Breezy told Tran during their argument that he used her in the beginning of their relationship to make RiRi jealous.

"He basically said the most messed up things to her ever," a source said. "Granted, they were in a heated argument, and Chris snapped and told her that 'When we first met, you were just a pawn in my game, and I was really using you to make Rihanna jealous.'"

The source said Tran has forgiven Brown, but "that will never escape her mind. Him telling her that, even though they both were arguing and saying things they shouldn't have, Karrueche felt like that cut her open and she's still bleeding from that."

Despite what he said to the model earlier this month, the R&B star recently told his longtime lover how much she means to him before their reconciliation.

"Chris told Karrueche, 'Bae, I'm about to man up. You've stolen my heart and no woman has ever treated me the way you have. No one, not even any of my exes compare to you. You're my queen,'" a source told Hollywood Life. "Chris also apologized to Karrueche, specifically for comparing her to Rihanna and lying about her and Drake dating."

The source added Brown promised Tran he would never compare her to Rihanna: "He was like, 'I don't know what I was thinking by saying that sh*t. Rihanna is nothing compared to you. You see I'm with you. I will never, ever compare you to her as long as I live. She doesn't even exist to me. You are my everything. Everything I am and have is because of you.'"

Meanwhile, Karrueche seemingly hinted at her engagement to Chris Brown recently. She took to her Instagram account on Christmas to share a photo of her right hand rocking two massive diamond rings. She captioned the image with a heart emoji.
