Even as a part of his act, the judges couldn't contain their excitement and amazement for Jones' astounding performance.
"You are truly, truly a superhero," Mel marveled, while Klum said the act was "really mind-blowing!"
Jones' toughest critic throughout the show has been Cowell, who has always praised him for his technical skill but criticized his stage presence and minimalist approach to theatricality. However, after Tuesday's demonstration, Cowell had nothing but love.
"It was magic! I thought your delivery was much better today, you were more confident. That's what it is about, stepping up for the semi-final," Cowell shared. "You know what, Eric? I think you're ready for the final."
