In the wake of Weinergate, Twitter brings us yet another bizarre online mystery -- this time, involving exes Chris Brown and Rihanna.

According to Bossip, Rihanna allegedly tweeted a response this week to a 2009 incident, in which Brown physically attacked her on their way to the 2009 Grammys.

"I admit, I provoked Chris to hit me. I't was not entirely his fault. #ImSORRY," the alleged tweet read.

The tweet is nowhere to be found on Rihanna's page, though Bossip posted a screenshot of it on Thursday.

The alleged tweet is making headlines the same week in which Brown sent a Tweet to Rihanna, asking, "You got that pic I sent you?" The tweet was removed almost immediately, leaving some to believe that it was meant to be sent via direct message.

This is just the latest chapter in the former couple's rocky saga. Last month, Rihanna received criticism from her fans when it was revealed that she was following Brown on Twitter.

Sound off: Do you think Rihanna's alleged tweet is real? Or is this all just another internet hoax?
