So, of course, when the pair appeared onThe Graham Norton Show to promote the movie, they continued to be their adorable selves.
When they were asked about the first time they met, John admitted that he was actually already a huge fan of Emily's work, and told her so immediately.
He even went so far as to reveal that he's seen The Devil Wears Prada MORE THAN 70 TIMES.
As we all know, The Devil Wears Prada is one of the most iconic cinematic works of the 21st century, so I don't really blame him.
But then Emily went one step further with the story, and supplied some proof that John truly is obsessed with The Devil Wears Prada.
Because he has a favourite outfit from that iconic montage of all of Andi's new fashionable outfits.
I mean, again, I can't blame him for having a favourite outfit. I'm pretty sure everyone has a favourite outfit from this scene.
Don't worry, though: John got his revenge and trolled Emily right back.
