Aaron Rodgers, Shaliene Woodley, Miles Teller and His Wife Keleigh Sperry Are All On Vacation Together? What?

What is happening here? As far as I know, Miles Teller and Shailene Woodley were in one* movie together, called The Spectacular Now. 

It's an extremely sad movie tbh. They date each other, Shailene is kind of a loser and Miles is Mr Cool Guy but also has a drinking problem. He's got family issues, daddy issues, the works. Shailene kind of turns into more of a caretaker than a girlfriend, and I won't spoil the rest. It's definitely a cry movie. But, it came out in 2013. 2013! And they're still good enough friends to be going on a couple's retreat with their new significant others? Did they ever have a relationship? Apparently Miles and his wife have been dating since 2013 themselves. What does he talk about with Aaron? What does SHE talk about with Keleigh? I'm confused, but this seems cool. Just a bunch of hot famous people hangin' out at waterfalls. Must be nice!

**Turns out Miles Teller was in a bunch of the Divergent movies with Shaliene. Didn't know that! Besties who work together, stay together.
