Chris Brown's model girlfriend Karrueche Tran has hinted their rocky relationship has come to an end yet again.

The couple has been dating on and off for the past few years, and on Wednesday (26Nov14), Tran suggested they have called it quits.

In a post on Twitter.com, she wrote, "Looks like I'm a single lady again."

Neither Tran nor Brown have made a follow-up comment to her post.

Earlier this month (Nov14), Brown gushed about Tran and their unique relationship, saying, "It's been almost five years. She's straight. I dig her man. She's dope... I feel like, especially being in this industry, you just need somebody that understands you; who understands who you are personally except for your name.

"Me and her have a real connection, like best friends on top of our intimacy. At the end of the day, me and her have a great relationship. We're best friends."
