Heidi Klum's singing debut on America's Got Talent definitely made headlines -- in more ways than one.

The 43-year-old supermodel impressed with her singing chops during a duet with Sal Valentinetti on Monday's America's Got Talent Holiday Spectacular, before taking a tumble mid-performance.

The mother of four was able to get a few lines of the duet in -- and impress fellow judges Simon Cowell, Mel B, and Howie Mandel -- before being twirled into choreographed spin by Valentinetti… followed by a not-so-choreographed fall.

Though Klum fell down on her back, she and her duet partner didn't seem to bat an eye, continuing their song like nothing ever happened, and earning a standing ovation from Cowell.

While Klum got into the holiday spirit for her AGT performance, it's only a matter of time before we see her back on another tropical getaway.

The Project Runway star recently opened up to Ocean Drive about her popular beach vacations, where she's often photographed topless -- and explained that she simply has no problem with nudity. 

"I grew up going to nude beaches with my parents, so I'm a nudist," Klum said. "I have no problems with nudity at all. I’m very free. When I go to the beach, it’s in a very remote place where there are not a lot of people, and I like to go topless."
