Madison Pettis is back for another round of lingerie selfies and we have Rihanna to thank for it! The actress has been working with Rihanna’s Savage x Fenty lingerie line for a while now and we always look forward to seeing some of the brands new designs on our favorite Fenty girl. This time Madison is showing off the new Chain Reaction micro slip, something we already saw Rihanna wearing but somehow looks..better? More Madison in the gallery!
