Chains and whips excite her ... and so do strippers, apparently!

Rihanna has tweeted several shocking photos of herself onstage at a strip club, and not only is she snapped doling out dollar bills to the dancers, but in one shot, a stripper's head is inches away from her crotch as a third female simulates oral sex in the photo. I guess RiRi really is a good girl gone bad!

"#RoleModelSh*t ... #ROCstarsh*t my daddy would be proud," Rihanna tweeted in one caption. Sigh. We hardly think Papa Fenty would approve of these pics!
