Three's a crowd -- especially when the three are Chris Brown**, Karrueche Tran, and Rihanna.

The trio have been tangled up in a messy love triangle for many months now, ever since Brown started secretly hooking up with on-again, off-again girlfriend Rihanna while still dating Tran, who works with the R&B star on his clothing line. Tran and Brown broke up in October but are continuing their relationship as business partners -- which has made it difficult for either of them to move on completely.

"I've been on a rollercoaster for the past year," Tran, 23, tells Vibe in a new interview.

That's an understatement. After Brown ended their romance last year, he posted a video to Twitter in which he said he was in love with both of his ex-girlfriends.

"When you share history with somebody, then you tend to fall in love with somebody else, it's kinda difficult," he said, admitting he was "a little drunk" in the clip. "Is there such thing as loving two people? I don't know if that's possible, but for me, I feel like that."

"It's a lot going on but it could be a lot worse," Tran tells Vibe of the ongoing saga. "And that's how I look at life. I take it for what it is. I move forward, grow from it, and at this point, that's what I'm doing. I'm not gonna sit and dwell and become consumed in that negativity, because I could very much be that person, especially when things are so public and so thrown in my face."

Indeed, Brown and Rihanna have been flaunting their rekindled romance all over Instagram and Twitter, with revealing pictures and messages to each other. Asked whether she would ever sit down with the two to work out her issues with them, Tran (who warred with Rihanna on the micro-blogging site last year) replies: "For everybody, emotionally, that would just be way too much. I'm a very mature person so if the time ever did come where we would need to sit down and talk, I'd do it. I'm a mature person. I can work it out but that would be a lot."

That said, the aspiring model/designer says she still loves her ex and wants him in her life. "At the end of the day, he will always be a friend," she tells Vibe. "We'll always care about each other."
