Jimmy Fallon had Kristen Bell as a guest on 'The Tonight Show' to promote her latest movie 'Frozen 2.' What better to way to promote the movie and the launch of Disney+ than to broadcast their talent and love for Disney? The two sang a medley of 17 Disney songs in just 5 minutes, and they killed it. Bell and Fallon wowed the world with their beautiful voices and committed performances and nobody can stop talking about it. @SandyLeeTV tweeted "Whooooa! Okay, @kristenbell just proved she could play all the Disney princesses! (Ariel anyone?!) Dayum! #sang #fallontonight"
