After being involved in a love triangle for years, Chris Brown is officially single. The troubled singer was recently in rehab for 90 days to deal with anger management issues. During that time, he attended hearings for the 2009 Rihanna assault case, and Tran stood by his side as he went to court to deal with his legal troubles.

But apparently that was not enough for the two to remain together. On March 12, Brown confirmed their split, tweeting to fans, “KAE will always be my heart. That ain’t changing. Just days prior, Tran had also written a message to fans, stating that she is “not dating anyone.”

Could Rihanna have something to do with this most recent split? Last month, Page Six reported that Brown “started texting Rihanna on her birthday [Feb. 20], and the two have been sending each other a flurry of texts ever since.”  According to the source, “Rihanna didn’t write back right away. ... But later that night she started getting sentimental and texted back, ‘thank you,’ and asked how he was. Since then, the two haven’t stopped texting each other and friends are freaked out that she’s going to start dating him again.” This would not be the first time Rihanna has caused the two to split up. Over the years, there have been numerous times Brown broke up with Tran to get back together with the pop artist.

However, this situation is even more messy since Rihanna is reportedly dating Drake, and the two were even spotted holding hands this week at an after-party in England.
