Rumors continuously suggest that Drizzy enjoys flirting with sexy groupies while RiRi works hard to promote her skyrocketing music career. And on Tuesday (May 27), the "Pour It Up" songstress posted this rather cryptic meme on Twitter:

@rihanna: "No flex Zone."

Hmm - is the 26-year-old pop superstar suggesting that she's actually single and ready to mingle once again? Maybe she's had enough of Drizzy's flirtatious ways!

Or is this just Rihanna flaunting her typical sassy attitude (something which usually turns Drake on)? Oh, the drama!

Earlier this Spring, Drihanna was basically inseparable. Things have simmered down since then, allegedly because the Nothing Was the Same crooner isn't paying enough attention to his Barbadian Queen. Do Mstars fans think RiRi finally dumped her on-and-off again YMCMB lover?
