“Twilight” star Ashley Greene should be attending every fashion show, given the amount of frocks she needs for her various worldwide film premieres. However, she chose Donna Karan as her one and only stop this week. “I do have so many events,” she told Buzz, “so I get to have fun with fashion.” The new global ambassador for Avon’s Mark cosmetics likes her new gig and wouldn’t mind another. “I think that if Donna Karan asked me to be her model, I’d do it in a heartbeat.”
