Say it with us: “Not again!”

Despite their multitude of problems, sources close to Rihanna and Chris Brown say there’s still a chance the tumultuous ex couple may get back together following months of secret on-and-off hookups and drama.

There may be one obstacle even bigger than the former flames’ history of abuse: Brown’s current girlfriend, Karrueche Tran. A source told Hollywood Life: ”They both still have feelings for each other but Chris is tired of the chase and sick of all of Rihanna’s manipulating of his feelings. She knows how to push his buttons and Chris is actually seeing that he has been taking Karrueche [Tran] for granted and wants to focus more on her, since Karrueche doesn’t bulls— him.”

The world thought the duo were donezo for good when Rihanna unfollowed Breezy on Twitter following his release of what may or may not have been a diss track aimed at her. Turns out, that’s just yet another ploy for RiRi to try getting his attention. “This Twitter thing was another Rihanna move to screw with Chris’s head,” the source said. “If history repeats itself, he will start talking to her again if he hasn’t already.”

The source does admit that the diss track and social media antics may have been the straw that broke Rihanna’s back, though. “If anything will make them lose their connection, it will be the song he did and this un-following fiasco,” the source dished. “It’s currently 50/50 on what the next stage of heir relationship will be.”

They’re both gorgeous and wildly successful, but sometimes two awesome people are just bad together. What in the world will it take for this toxic twosome to move on? It’s not like they can’t each get any man or woman on the planet that they wanted!
