Porcelain performed single 'This is What Rock N Roll Looks Like' for Letterman and his late-night crowd, whipping around her two-toned, Cruella De Vil-inspired coiffure and cranking out some racy choreography.
Porcelain wore a leather, leotard-like bustiere number, complete with mesh, fringe and metallic studs. Apparently, "this is what rock 'n' roll looks like!"
Wayne rhymes on the studio version of Black's raspy track and appears in the music video, but left Porcelain to make her debut TV appearance on her own.
