Viewers knew they’d get an unforgettable moment when Heidi Klum took the stage during America’s Got Talent Season 11 — but nobody could’ve predicted just how memorable it would be.

On December 16, the former Judge turned back the clock and shared a 2016 video clip of her epic “Santa Baby” duet alongside her Golden Buzzer-winning Act, singer Sal Valentinetti. It was the perfect way to celebrate the holiday season. If you’ve never seen this performance, you’re in for a treat. Watch Heidi Klum’s AGT Season 11 duet of “Santa Baby” here.

“This is still one of my fondest Christmas time memories from @agt singing with my golden buzzer @salthevoice ❤️,” Klum captioned the throwback video.

The performance began with Valentinetti showing off his Frank Sinatra-esque vocals as he walked across the stage. It was a genuine winter wonderland with gingerbread men providing the musical accompaniment.

Before fans knew what was happening, Klum began descending from high above the stage atop a giant candy cane. She then shocked the world by singing in a sultry, pitch-perfect fashion as she helped Valentinetti bring “Santa Baby” to the next level.

Who knew Klum had this level of vocal talent?

The duo even showed off their dancing skills, with Valentinetti spinning Klum around the stage — until Klum tripped and fell in a heap! It was a moment that shocked viewers and Judges alike. Simon Cowell looked especially worried. However, the stunt was intentional and Klum never missed a beat, finishing off the duet with ease.

It was magical and exactly what AGT has been all about for the past 20 seasons. You never know what kind of talent we have inside us, whether we’re performing on stage, watching at home, or sitting next to the Judges.

When was Heidi Klum a Judge on AGT?

Klum joined AGT as a Judge in Season 9 and participated in every season through Season 19, save for Season 14 when Julianne Hough temporarily replaced her.

(Klum would return in Season 15, coinciding with the debut of her BFF Sofia Vergara, who is still part of the AGT family today.)
