Hugh Jackman Was "Busted" Singing at a Greatest Showman Screening, and the Video Is Priceless!

The Greatest Showman made its theater debut last year with one of the greatest soundtracks we've heard in a while. It's so great, in fact, that select theaters have been hosting singalong screenings (trust us, it's as fun as it sounds). Well, what would you do if in the middle of belting out "The Greatest Show," you turned around to see the P.T. Barnum — excuse us, Hugh Jackman — singing right along with you? "Freak out" is the appropriate answer.

On Friday, Jackman shared a video on social media of him inconspicuously singing along in the movie theater . . . that is, until he got "busted." Showgoers were in for the surprise of a lifetime, and by the look of the video above, they absolutely loved it. Check out some reactions below from people who were lucky enough to witness P.T.'s greatness in real life, and others who totally wish they did.
