Emmy Rossum made sure she was in top shape to present at the Tony Awards.

Spies said the actress showed up “15 minutes early” to an 11 a.m. dance class at AKT InMotion on the Upper East Side Sunday morning.

“The class was filled with all advanced students who had been learning dance choreography for two weeks,” a spy said.

“[But] Emmy then jumped right in and nailed it immediately.” She even “hooted and hollered” and was “extremely focused the entire hour.”

But the star pupil was overheard admitting, after she left mortal dancers in the dust, “I am ready for a nap.”
