Rihanna Flaunts Underboob... For Chris Brown?!

What's going on with Rihanna and Chris Brown? They love being naked, we already know that, but everywhere?

After the sex tape scandal, they seemed to be calmer, however, Rihanna has had a crazily busy week posting a bunch of photo on Instagram, like the one above.

Apparently, Rihanna has been posting photo on the social network, probably in order to tease Chris Brown, right after she uploaded a picture dissing him.

We know her track record, but do we know his? I'll get it for you!
