During her appearance, Emily shares that she was shocked when she got the call to star in the movie from director Rob Marshall.

She talks about the highly-anticipated sequel to the 1964 musical and working with Dick Van Dyke. Then, after Emily admits she has a fear of singing in front of an audience, Ellen encourages her to face her fear and sing “I Want It That Way” with the help of the Backstreet Boys.

Plus, Ellen tests how much we really know about the boys of BSB in a game of “Never Have I Ever.” They also perform “Don’t Go Breaking My Heart” from their upcoming album DNA.
