This never gets old....

Beautiful Heidi sing, she most Beautiful young , she is the nicest judge God give her long life, lucky her family,children and oooooo ? .

And yes, she did fall on purpose. Watch the way she slings herself away from him. He doesn't push her away. Then, she pulls her hand out of Sal's, spins around one full turn, and sits down with her right leg under her, in perfect postion to keep singing and without "showing anything" to the audience. My guess is Sal wasn't in on it, and they were doing it just to put one over on him.
