First off, let’s remember– Jessica Biel and Jimmy Fallon are friends in real life. They have a connection. They have chemistry. That’s what you need to play charades. Kelsea Ballerini likely had never met her partner, Matt Bomer. Apparently he’s an actor, but– who knows?
Kelsea is good at a lot of things, but charades with this Matt guy is not on that list. Unless the clue is a Justin Timberlake song and she’s playing against Jessica Biel.
