Chris Brown and Karrueche Tran have split again, and this time things are turning ugly. The couple called it quits last week, but they are airing each other's dirty laundry on social media. It all started when Tran announced on Twitter that she was single.

Brown confirmed the news Friday night at the Cali Christmas concert telling the audience, "I'm single now, f**k that b**ch." Tran responded with a jab at the "Love More" singer on Twitter, and told her followers that Brown was upset because she dumped him.

The 25-year-old singer fired back with a lengthy tirade on Instagram where he accused Tran of cheating on him with Drake.

"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 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! When this relationship first started u knew what it was and even participated in threesomes. I slowed all that shit 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**as ain't shit and focus only on themselves. I made it clear to the world who my girl was and made your life equal to mine eve at the cost of me not focusing on my career at times. So miss me with the bulls**t. now yall know the real."

He also wrote, "It amazes me that you can change and elevate somebody's life completely and they treat you like a regular n***. BUT IM SLEEP."

Drake hasn't responded to the allegations, but if Brown's claims are true, this would be the second time Drake has slept with one of Brown's former flames. He also hooked up with Rihanna after she split from Brown.

Tran also ranted about the relationship on Instagram and claims that part of the reason they broke up was because Brown "mistreated" her.

"Once you find strength within yourself, it's hard to allow any type of bs around you. I refuse to be repeatedly mistreated especially by someone who claims to love me," she said. "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."
