"America's Got Talent" judge Howie Mandel gushed over the Mayyas' semifinals performance after the show on Tuesday, while contestant Kristy Sellars said the judges' reactions to her pole dance act were "amazing."

On the red carpet, Sellars told Fox News Digital that judge Simon Cowell, 62, had talked to her after the show about "an opportunity," but didn't disclose any further details. 

During the show, Cowell also declared that the Lebanese all-female dance group, the Mayyas, "is a performance that changes the world." Mandel expressed his enthusiasm for the Mayyas as well while speaking with Fox News Digital. 

"That was my favorite moment of the night," the 66-year-old television personality said on the red carpet at the Sheraton Pasadena Hotel in Pasadena, California.

"I have never seen such professionalism, such creativity, such authenticity. You are seeing 36 people come together and become one hypnotic, powerful, beautiful creature that I could have watched for the entire two hours."

The Canadian comedian continued, "I don't care if I didn't see anything else tonight but the Mayyas. That was my favorite thing I have ever seen. And add to that, where they come from and who they are."

Mandel explained that as the father of two daughters, he believed that the Mayyas' performance and their stated mission of female empowerment would be inspiring to women all over the world.

"I believe in female empowerment and equality," he said.

Mandel then addressed a Lebanese media outlet, saying, "I think in your part of the world that's even a bigger issue sometimes."

He added, "I'm not knocking anybody's culture, but it's harder for them and you to do the things that you want to do and be as creative as you want to be so that added power to where my heart was just pounding"

"This is just amazing. As Simon says, this will change the world and if nothing else, it will change their world and people's impression of your world."

Later in the interview, Mandel joked as he explained how he had managed to remain successful in the entertainment industry over his 45-year career.

"I'm very, very good at what I do," he quipped.

"Thirty-six women dancing as one — it’s magic," the "Modern Family" alumna, 50, said.

Heidi Klum, 49, told the Mayyas, "I feel you are Vegas ready."
