Rihanna serves up more scintillating stills from her “S&M” video shoot with director Melina. In the latest photos, the big-haired diva can seen lounging on an office desk in a pink latex cocktail dress surrounded by the prying press. For another look, the Playboy bunny, wearing a hip-hugging getup, black stilettos, and yellow ears atop her flowing crimson locks, reclines against a wall covered in tabloid headlines. There’s no stopping her now!
