Hours after the singer, 23, confirmed is split from Tran, Brown posted a video on Twitter titled "The Real Chris Brown."
In the clip, Brown admits he's "a little drunk" but says he wants to set the record straight about falling back in love with Rihanna, 24, while still dating Tran, 23. "Y'all don't really get the real Chris Brown, so I like to just be honest, man. I'm stressed out," he says. That's just real (expletive), man."
Brown adds, "When you share history with somebody, then you tend to fall in love with somebody else, it's kinda difficult. Is there such thing as loving two people? I don't know if that's possible, but for me, I feel like that."
"Y'all are probably like, 'What the (expletive) is he talking about right now?' But I'm just saying, I'm being real. I don't want to hurt either or. I'm not trying to be a player. I'm not trying to be a dog. None of that. My mama raised me differently. I just can't. It's too much sometimes."
When Brown first confirmed his split to Us Weekly, he said he had "decided to be single to focus on my career. I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna. I'd rather be single allowing us to both be happy in our lives." Brown and Tran dated for about a year.
After Brown's video went viral, an emotional Tran expressed her heartbreak via Twitter. "What the (expletive) is going on?" she wrote. "All I'm saying is, you don't mess with people's genuine feelings. You just don't!"
Pre-split, Tran and "Diamonds" singer Rihanna frequently traded insults over Twitter. According to sources, Tran says she has long been aware of Brown's recent relations with the pop star.
Even after Brown assaulted her in February 2009, Rihanna believes he is "the love of my life." During the August 19 episode of Oprah's Next Chapter, the singer said Brown feels the same way. "We love each other and we probably always will, and that's not anything that we're going to try to change."
