Chris Brown's love triangle with Karrueche Tran and Rihanna seems to be back in full effect, after rumors swirled that he dumped his model girlfriend for the Bajan beauty. 

According to Radar Online, Brown has broken up with Tran, who has stuck by his side during his 90-day stint in rehab to be with Rihanna. Brown is also said to have unfollowed Tran on Twitter. 

Last week, The Kill designer took to Instagram to post a picture of herself holding up a sign that read, "Treat Your Girl Right."

The report comes days after Page Six reported that Brown and Rihanna were nonstop texting each other.

"Chris started texting Rihanna on her birthday [Feb. 20], and the two have been sending each other a flurry of texts ever since," a source close to the singers said. "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," the source explained. "Since then, the two haven't stopped texting each other and friends are freaked out that she's going to start dating him again."

While Brown attempts to sustain his personal, he's still facing legal issues after a judge ordered him to stay in anger-management rehab for two more months. 

Documents revealed by TMZ prove that the Love More singer has been diagnosed with bipolar disorder, severe insomnia and post traumatic stress disorder (PTSD.)

Brown is now getting proper medication to treat Bipolar II and his other issues. He is due back in court on April 23.
