Demi Lovato joined Jimmy Fallon for a hilarious round of the Best Friends Challenge this episode of “The Tonight Show.”

The rules of the game are simple: players take turns pulling out questions from the Best Friends Box and then scribble down their answers on a notepad. The aim is to write down the same answer as your partner — it’s like “The Newlywed Game,” only dumber.

Jimmy and Demi’s questions involved guessing which Disney princess Jimmy would be, what item Demi would bring with her if she were stranded on a deserted island, what TV show they would binge watch together, and what their combined best friends forever moniker would be.

Here’s Fallon playing the same game with Lovato’s fellow pop star Ariana Grande:
