As reported by AOL Music, earlier this week, rumors hit the web that Rihanna and Chris Brown have been indulging in a secret romance for the past year despite their tumultuous past -- not to mention Breezy's new girlfriend Karrueche Tran. Now, a recent tweet from Rihanna has increased speculation that Ri, Brown and Tran have one messy love triangle on their hands.

The tweet was originally posted by a hip-hop fan and later re-tweeted by Rihanna. The message read, "#TheresNoReason to cheat, there never is. If you're not happy with the relationship then don't be a coward, just end it."

Is Rihanna -- who would be the "other woman" in this case if the rumors are true -- suggesting that Brown call off his romance with Tran so that she can have C-Breezy all to herself?

A rep for Brown has addressed the Rihanna rumors, insisting the two are "just friends" and claims Chris is not cheating on his aspiring model girlfriend. On the flip side, insiders are reporting that Karrueche is well aware of Brown's infidelity, but isn't bothered enough to break up with him.

Rihanna and Chris will both attend the 54th Annual Grammy Awards on Feb. 12, so we'll have to wait and see if a run-in between the former lovers reveals any of the rumored reignited romance!
