Chris Evans can take out bad guys any day of the week as Captain America [1], but when it comes to a simple request from his Gifted [2] costar Mckenna Grace, he's powerless. The adorable pair stopped by The Ellen DeGeneres Show on Monday, and Ellen let it slip that Chris once took tap dancing lessons. Mckenna, 10, then sweetly pleaded with Chris to tap for them and the audience, and he couldn't resist. Of working with Chris, Mckenna also confirmed that "he's so nice," in case you have any remaining reservations about what a wonderful human he is [3].
