Chris Brown and Karrueche Tran have called it quits. Hollywood Life reports that the 26-year-old model announced on her Twitter account that she is now back on the dating market.

Tran tweeted on Wednesday, November 26: "Looks like I'm a single lady again."

Tran's romance with the 25-year-old singer had been through some ups and downs. According to Hollywood Life, she supported Brown during the instances "he needed her the most," including the time when he went to rehab.

The gossip website also stated that before the alleged breakup, Brown and Tran had been living together and that "they had big plans for the future." She even went to couples therapy with the singer so that they can move forward with their relationship.

According to Hip Hollywood, Tran even unfollowed Brown on Instagram. There were claims that he was caught cheating on her, and that "evidence of Brown's transgressions include a screen grab from a video clip that shows the singer laying in bed with the woman." It has not been confirmed if the man in the video was Brown, but Gossip Cop added that the speculations were based on the "back tattoos [of the singer], bedroom décor, and clothing visible."

When Brown appeared on Hot 97's Ebro radio show on October 31, Brown opened up candidly about his relationship with Tran. Asked about how long they had been dating, the "These Girls Ain't Loyal" singer said, "Almost 5 years ... 4 1/2."

"She's straight. I dig her, I dig her man, She's dope. I feel like especially being in this industry you need someone that understands you and understands who you are personally except for your name. You don't have to be buying them bags, let me stunt on you right quick. Although I do it because I love her, but that don't come with the territory, at the end of the day we have a real connection as best friends on top of our intimacy," Brown added, as quoted by another report from Hollywood Life.

Brown also said in the interview that he plans on marrying Tran one day, but not right now because he is scared of marriage. He is also open to the idea of kids and having "a little Chris Brown," although he said that he is not in a rush for that.

But Brown reportedly confessed that he's still in love with ex-girlfriend Rihanna even though he was dating Tran at the time, Hip Hollywood noted.

Does this mean that Rihanna and Brown will be back together?
