Rihanna and clothes go together like Chris Brown and pristine records of conduct.

Ahem.

In any case, while Brown allegedly spent the weekend concerning himself with Frank Ocean's parking space, the "Stay" singer was also back to it over the weekend, taking to Twitter to show off not only her newly cropped cut (after a brief flirtation with long, flowing locks), but also some sexy, topless photos of her latest "top secret" project.

"And that's a #wrap on my shoot for my new #topsecret add campaign!!!" Rihanna tweeted. "#2013 #phuckyobasic."

The superstar didn't stop there, and posted a zoomed-in beauty shot of herself, again teasing fans with, "#RIHpost sneak peek of my shoot today with @mertalas."

There's no word on what campaign the new photo shoot may have been for, and her attire (or lack thereof) certainly isn't giving us any hints—aside from her perfectly matched nails and lips and impeccable makeup, RiRi donned nothing more than a modesty-covering white towel and Chanel jewelry for the shoot.

But whatever it is, it's going to be hot.
