Only a few days before the Oscars, a big-time fan at a Michael Bublé concert had a made-for-TV moment right out of “American Idol.”

While speaking with fans during his Madison Square Garden show, Bublé asked 21-year-old Erin Bellucci to perform her favorite song.

Shaking with excitement and anxiety, Erin took the microphone from Bublé. With all eyes and cameras on her, the music major at the University of Delaware proceeded to shock the crowd with her soulful rendition of “At Last.”

“I was stammering, but then I heard the music,” stated Erin. “I’ve sung that song so many times, they had the piano ready to go, and I knew I had about 30 seconds to sell myself.”

Let’s just say this vocal powerhouse did not let the crowd down. The crowd-pleaser left the audience and Bublé in awe.

“That was so beautiful,” said Bublé when he got the mic back in hand. “That may not be your last time here. That was incredible.”

Thankfully, Erin’s sister Allison Bellucci caught the once-in-a-lifetime moment on camera. Check it out below!
