"This is how we always go to the movies, just like this," Theroux joked with ET's Cameron Mathison at the star-studded premiere. "We put on tuxedos and go to the movies like this."
Zoolander 2 hits theaters this Friday, just in time for Valentine's Day weekend. While fans will likely going to see the long-awaited comedy on date nights of their own, Theroux said he's got some pretty big plans in store for his wife.
"We're going to probably have a romantic date night. Her birthday falls like three days before so I'm just wearing out my credit card on her birthday and then that," the 44-year-old actor shared.
ET briefly caught up with Aniston as she made her way into the premiere, where she revealed that it would be her first time watching the film, which Theroux co-wrote and also has a cameo.
Theroux reprises his role as the evil DJ from the first Zoolander film and to kick off the premiere, the actor was in full costume -- complete with long dreads and shiny golden sneakers.
While Aniston didn't get to see her hubby in his full evil DJ regalia, she did praise him for being "multi"-talented.
