Karrueche Tran and Chris Brown have called it quits – again!

On Friday, Dec. 5, the “Deuces” singer made headlines for publicly announcing he is a single man. Now, several media outlets are speculating about what led to the demise of their relationship.

For those who missed it, the 26-year-old model supported Chris throughout his rehabilitation stints and legal woes.

So, many fans thought their relationship was rock solid since they survived so many pitfalls. However, the recent news shows that definitely is not the case. So, what could have led to their catastrophic downfall?

According to Vibe Magazine, rumors have surfaced about Karrueche’s alleged cheating.

Apparently, she wasn’t faithful while the Grammy Award-winning singer was in rehab. But, that’s not all!

She has also been accused of cheating on Chris with famed YMCMB rapper Drake! Although the rumors have yet to be confirmed or denied, Chris and Karrueche took to Twitter and Instagram with allegedly subliminal messages about their break.

Then Chris fired back with a jaw-dropping response to his ex-girlfriend’s post. In addition to taking credit for “changing and elevating” Karrueche’s career, he also accused her of having a threesome and taking trips with the “0 To 100” rapper.

However, all of the messages have since been deleted. But, that doesn’t mean any accounts were hacked because Chris made the same announcement during his concert on Friday night.

He definitely had no reservations about bashing his ex-girlfriend and made it quite clear that he is a single man.

The shocking rumor only adds fuel to the fire because Drake and Chris aren’t exactly best friends. Unfortunately, this isn’t the first time they’ve been involved in an alleged love triangle with a woman. Last time, Rihanna was the center of their dispute. So, did Karrueche Tran really cheat on Chris Brown? No one really knows. Only time will tell if she really did.
