Why, an adorable bromance, of course! While we want to think Tina Fey and Amy Poehler had something to do with this longterm friendship…though it was probably more like Hamm's partner, Jennifer Westfeldt. She cast the two gents in her film, Friends With Kids.
The two actors were seen catching a movie with their significant others in Los Angeles on Thursday night.
The group of four saw Wolf of Wall Street at the ArcLight Hollywood and appeared to be all smiles after the Martin Scorsese drama.
Hamm was seen in a casual outfit of jeans, a sweater, worn-in leather bomber jacket and a baseball cap.
His partner Westfeldt wore a burgundy coat to keep herself warm and clutched her leading man's hand as they walked to their car.
Meanwhile, the Parks and Recreation funnyman opted for a similar look of jeans and a blue jacket.
His wife Naomi seemed to match her hubby in a black-and-gold jacket that was a similar style.
The two stars worked together back in 2012 on Adult Swim's hilarious show dubbed the Greatest Event in Television History, as well as Westfeldt's film, in which she and Scott play friends turned lovers.
Scott is currently promoting his latest film, The Secret Life of Walter Mitty, which hit theaters everywhere on Christmas.
