Chris Brown is single… again. The singer, who is focused on his rehab and his new music, like his duet with Ariana Grande, has split with his long-suffering, on-off GF Karrueche Tran. Is Rihanna to blame?

The news that Breezy and Tran were dunzo actually came from Tran herself. She tweeted that she is not dating anyone and asked her followers (or maybe the media) to chill with the nonsense and BS.

This confirmation that she is flying solo and is a la carte comes after a report that Breezy has been reaching out to RiRi. Remember, Breezy dumped Tran, who he first began dating back in 2011, to reunite with Rihanna last year. They split again and Breezy ran back to Tran, who was by his side during many of his legal issues and court dates.

The New York Post reported that ChRihanna were constantly texting one another since her birthday (Feb. 20). His rep shot down the latest Rihunion rumors, saying that Breezy is "focused about his recovery. He only wants the best for her."

Breezy and RiRi are forever linked via two triangles. Breezy, RiRi and Karrueche and Breezy, RiRi and Drake. It's never-ending with ChRihanna

Meanwhile, anyone else think this Tran photo is Rihanna-influenced? Look at her hand.
