Will Arnett and Jason Bateman starred together in four seasons of Arrested Development, and it looks like their relationship progressed to real-life too. It's hard to tell who's harboring the crush here, but Will once joked that he and Jason were dating:
“Jason and I were just looking to have a little pied-à-terre in the city. And look, we’re not dating per se. And obviously she—he would like to."
