The 42-year-old actress was in New York City just up until the day before the awards show as she is in rehearsals for her new Broadway show If/Then, which begins performances TOMORROW.
Idina told the crowd that the version she was singing was edited down to fit in her time slot. She also had a little lyric flub during the performance!
After getting back to New York after the Oscars, Idina made a special visit to The Tonight Show Starring Jimmy Fallon for a very cool performance of the song.
