Aubrey O'Day will walk the runway for Heatherette designer 's new collection during Fashion Week, the Danity Kane singer revealed at last night's Traitor premiere. "I’m walking in Richie Rich’s new line. He was from Heatherette, now he’s got a line called, um … Celebut…," she turned to her friend to ask. "I think it’s Celebutante." RIGHT... Diddy taught her well: Correctly stating the name of that which you promote is paramount to modern-day celebrity success. "Lydia Hearst and I are the new models for the line, so we just shot that a couple days ago, and I’m walking in his show on the 9th.”
