What movie is this scene from?

A fairly recent movie, I’m thinking maybe something like “Bring It On”, featuring kids dancing/planning to dance/leading up to a big danceoff. Maybe cheerleading is in it, too. … All I can remember is a young woman, an empty stairwell, a - teacher? - anyway a slightly older man. They’re talking about dancing and he reveals to her he is a regular Fred Astaire by doing a quick tap routine on the stairs. Just a curiosity rattling around in my mind.
