Even Justin Theroux, who co-wrote the long-awaited comedy, showed up as his Zoolander 2 character, the evil DJ, complete with long dreads, a gruesome face scar and some of the most epic golden, winged sneakers ever.

After walking the runway, the 44-year-old actor even got behind the DJ booth to blast some music for the show.

Theroux later appeared (sans costume) with his wife, Jennifer Aniston, and the two looked simply adorable walking the carpet hand-in-hand and cozying up for the cameras. Aniston stunned in a burgundy Galvan gown.
