Here's a short story:

(CNN)Things have been messy between singer Chris Brown and his now ex-girlfriend Karrueche Tran, and it looks to be about to get messier. 

Oprah Winfrey's network, OWN, posted a teaser Tuesday for Tran's interview with Iyanla Vanzant. The inspirational speaker and host of "Iyanla: Fix My Life" fires off at Tran: "He betrayed you. He lied to you. He did it all publicly," before asking, "How did you find out that he had a baby by another woman?" 

Brown has been the subject of rumors that he fathered a daughter with another woman while in a relationship with Tran. He has neither confirmed nor denied the stories, but the story heated up when Tran tweeted on March 4, "Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me." 

The tweet was later deleted. 

Brown and Tran have had an on-again, off-again relationship for years. In 2012, Brown posted a video on Twitter questioning whether it was possible to be in love with two people. At the time, the singer had broken up with Tran after once again growing close to singer Rihanna, whom he assaulted while they were dating in 2009. 

"I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna," Brown said in the video. "I'd rather be single allowing us to both be happy in our lives." 

Brown and Rihanna eventually reunited but then broke up again, and he and Tran, who bills herself as a model and entrepreneur, resumed seeing each other.  (End of story)
