The crowd went wild after the Valentino show at Paris Fashion Week on Tuesday afternoon, and it wasn't because of the clothes.
Actors Ben Stiller and Owen Wilson closed out the show, reprising their roles as male models Derek Zoolander and Hansel from the 2001 film "Zoolander" in a runway "walk-off" that announced the sequel to the film.

After the conservative-looking Valentino runway show -- which was inspired by artist Celia Birtwell and swinging London, but looked more like church clothes with long sleeves and patchwork lace -- the crowd erupted at the surprise appearance by Stiller and Wilson.
As Zoolander, Stiller wore a custom Night Butterflies brocade suit with hand-embroidered overcoat and Creeper shoes. Wilson wore a silk contingent print pajama suit with double cashmere overcoat and sneakers.
Some said it was the best part of fashion week.
A representative from Valentino said the top secret deal has been in the works for months, and it's not known if the scene will appear in the film, which is shooting in Europe this spring and scheduled for release February 12, 2016.
