Rihanna’s Tits Hit Instagram

We can never say no to near-nudity from Rihanna, especially when it comes from the bastion of sin and naughtiness that is her Instagram. Meanwhile, her Twitter account is far less fun, since she recently tweeted a photo of her with an IV in her arm.

We don't normally think of ourselves as a celebrity gossip site, but we can't resist the urge to drum up some sensational stuff like, "Is Rihanna exhausting herself? She's been showing a lot of boob but no nipple; is this taking a toll on her body? And what does her label think of all this?"

Uh, anyway, we hope she's feeling better and we love her pictures. Yay.
