Ben Stiller and Justin Theroux aren’t wasting any time in getting plans for “Zoolander 2” up and running. The “Meet the Parents” star and Theroux, who worked together on “Tropic Thunder,” stopped by Matsuri in Chelsea to discuss the sequel to the hit fashion spoof, which was recently given the go-ahead by Paramount. “Justin had mentioned doing research on the modeling world in Paris for Fashion Week,” a spy reports. Theroux is slated to direct.
