America's Got Talent: All Stars aired its penultimate episode on Monday night, which saw all 11 finalists give it their all with incredible performances ahead of the finale next week.

The 18-year-old was the last contestant to take to the stage on Monday and after dedicating his performance to his late grandmother, who recently passed away, he wowed the audience and judges alike with his incredible skills.
The self-taught aerialist was met with a standing ovation after flying through the air without a safety net while attached to a strap that hung from the ceiling.
While Heidi Klum said Aidan was in a "different league of aerialism", Howie Mandel added: "You combine such stunning danger with elegance and grace and contortion and dance. I have never seen anything like that in aerialism before. You just set the bar."

Simon went on to say that Aidan's performance reminded him of when gymnasts in the Olympic games give such an incredible performance that they are awarded all tens by the judges.
"I have never, ever, ever on a movie, on this show, anywhere, seen anything so incredible as that and so dangerous and so brilliant and so well-coordinated," Simon said.
