The “Umbrella” singer can add one more title to her ever-expanding resume — runway model. After performing in Toronto, Rihanna headed to Milan were she walked DSquared’s Fashion Show in a very sexy lingerie-inspired dress and killer high heels. The singer strutted herself like a pro — even closing the show with the designers. The lingerie look seems to be a Rihanna favorite, from her dominatrix-like tour gear to the sexy separates in her new music video Hate That I Love You (in which shes dons little else except for some major Kwiat Diamond jewelry). Look out Giselle and Naomi, this singer could be stepping on your heels very soon.
