The Mirror reports that Blake Lively stopped by Victoria Beckham's spring 2010 presentation in New York last month with Gossip Girl costume designer Eric Daman. They confessed mutual love for one another, and Blake eventually convinced Posh to make a cameo on the show. She will reportedly grace New York Wednesday to film her scenes. A source says, "She isn't an actress and wanted her role to be very tongue-in-cheek. And an idea for her to play Brit actor Ed Westwick's long-lost mother was quickly vetoed. Victoria joked that she'd rather play his ex-love interest!" [Mirror UK]
