American singer Chris Brown has accused Karrueche Tran of cheating on him with rapper Drake.

Twitter user Blogxilla tweeted that the 25-year-old R&B star confirmed he is single at the Cali Christmas concert.

Following that, the Say Goodbye singer took to Instagram and posted a cryptic message about breakup, which he then promptly deleted.

Brown wrote: "We've got scars, some of them u gave me, some of them I've caused. That ride or die act we have been fooling the world with obviously ain't working. I was locked up for damn near 4 months and only got 1 visit from you while u was hosting parties and taking secret trips to Toronto, going on dates with Drake!" [sic]

"When this relationship first started u knew what it was and even participated in threesomes. I slowed all that sh*t down. So let's not try to save face for public opinion because I don't need to play victim so people can take my side. All these celebrity n*ggas ain't sh*t and focus only on themselves. I made it clear to the world who my girl was and made your life equal to mine even at the cost of me not focusing on my career at times." He added, "So miss me wit the bullsh*t. Now yall know the real," he continued.

Meanwhile, the 26-year-old model also took to the photo sharing website and admitted she has made mistakes, but she refuses to be "mistreated".

Tran's message on Instagram read: "Once you find strength within yourself, it's hard to allow any type of bs around you [sic]. I refuse to be repeatedly mistreated especially by someone who claims to love me. That's not love. And if that's what you define as love then I don't want it. Yes, I have not been so smart before in the past but I made a promise to be a better and stronger woman and I'm keeping that promise. If you can't love me the right way, then don't love me at all. Don't be mad at me because I prefer to be happy. Keep love in your life folks. Not just love between people but love within your HEART, flowing in all aspects of your life. I promise life is so much better."

This comes after Tran raised eyebrows after she posted a cryptic Twitter message stating that she is single.

She wrote on the microblogging website: "Looks like I'm a single lady again?"

However, Tran later clarified the tweet and revealed that she has joined American comedy-drama television series, Single Ladies on VH1.
