Harry Connick Jr. should definitely get a ticket to Hollywood for this American Idol audition!

In a new 'Idol Moments' video posted on YouTube, the 47-year-old crooner hilariously sings Sia's popular hit "Chandelier" for fellow judges Jennifer Lopez and Keith Urban!

And though the teaser video for the show's upcoming season — which premieres on FOX on Wednesday, Jan. 7 — is only a mere 20 seconds long, you'll definitely be laughing out loud at Harry's silly antics.
