Oops! Heidi Klum takes a tumble onstage as she makes her singing debut on AGT Holiday Spectacular 

Taking a fall on national TV is pretty embarrassing - that is, unless you're Heidi Klum.

On Monday's America's Got Talent Holiday Spectacular, the supermodel took a serious tumble mid-song as her duet partner, Sal Valentinetti, twirled her around.

Exposing her mile-long bronzed legs in the air as she fell to the ground, the 43-year-old didn't skip a beat as she sat up, posed gracefully, and continued to perform.

Ouch! Heidi Klum, 43, takes a bad fall during her singing debut on the America's Got Talent Holiday Spectacular stage Monday night 

Only her: The international supermodel made falling look sexy as her dress fell to expose her mile long legs

The stage was made to look like an ice rink - and may have been a contributing factor to the bombshell's accident.  

Though Valentinetti can be heard asking if Heidi is okay, the duo's background dancers don't blink an eye or stop their choreography.

This lead social media to believe the fall was planned, regardless of the stunned faces of the judges and audience.

As she wore a red Christian Siriano gown, the Emmy-award winner wasn't half bad performing the duet of Eartha Kitt's 1953 song Santa Baby with Valentinetti.

The 21-year-old jazzy crooner just so happened to be Heidi's golden buzzer pick from season 11, which concluded on September 14.

Klum easily managed to talk-sing the sultry track with her whispery soprano vocals, and she even did a harmony with Sal for the big finish.

The German-born model's festive serenade during the pre-taped two-hour special got the notoriously hard-to-impress judge Simon Cowell up on his feet for a standing ovation.

'I love singing, but I'm not a singer like Sal! I'm hoping the other judges don't press their X buzzers on me,' Heidi told Billboard ahead of the show.
