As part of their never-ending promotional tour for their latest album, ‘Four,’ One Direction were interviewed by Jimmy Fallon on ’The Tonight Show' last night (Dec. 23), and in true 1D fashion, it was totally adorable.

In the first part of the interview, Jimmy mentions that while it’s One Direction’s first time on the show all together, Harry had stopped by before. He was, of course, referring to the time Kristen Wiig dressed up as Harry for the show, but Harry was a great sport and totally played along anyway.

When asked about the boys’ holiday plans, the conversation naturally steered toward the topic of food — specifically Harry’s love and appreciation for yams with marshmallows melted on top and how much he wishes that were an English food tradition.

After discussing the boys’ upcoming world tour, Jimmy showed them the vinyl version of ‘Four,’ and one thing leading to another, the six of them decided to hang out on the floor for the rest of the interview. Jimmy launched into his best English accent, to which Niall responded: "I didn’t realize Prince William was on the show.”

Our favorite part? Jimmy thanked the boys on their album and, perfectly on cue, Harry responded with “Congrats on your child!” to which Jimmy totally lit up and said, “She likes you guys.” Because she clearly has impeccable taste, despite being only a few weeks old.
