America's Got Talent judges argue over contestant's incredible balancing act: 'What are you talking about?'

It's not very often that the America's Got Talent judges seriously disagree with one another, but that's what happened Tuesday with contestant Praveen Prajapat, whose amazing act left Heidi Klum, Howie Mandel, and Sofia Vergara in awe, but Simon Cowell just meh on it.

Prajapat, who hails from India, introduced his performance by explaining that his father had taught him the mysterious act, which comes from a culture thousands of years old, when he was around 10 years old. His dream, he said, is to perform around the world.

"I have trained two or three hours every day for the last 10 years just for this moment," he told the judges.

Cut to Prajapat stacking four glasses of water and a pot on top of each other on his head. If that weren't amazing enough, he also stood on one leg and hopped around in a circle — all while balancing the objects. He then upped the stack of glasses and walked around the stage, even stopping for a small shimmy.

This is where the trouble started.

Klum was the biggest fan.

"I love that you bring us a little taste of your beautiful country here to America and it was just beautiful to watch," she said. "It was super exciting, and you are just so handsome to look at."

Mandel declared, "We've never seen anything like this before."

Vergara, too, was impressed.

"It's so difficult to do what you were doing. It was definitely one of the most amazing acts I've seen on AGT," she said. "I think you're gonna do very well in this competition."

But Cowell was not as compimentary.

"OK, well, look, I thought it was pretty amazing," he said. "I'm just wondering what would you do next?"

Turns out that Prajapat can balance many more items on his head, but even that didn't move Cowell.

"I like you very, very much," he said. "However, I'm gonna be honest, that didn't excite me enough, so I’m gonna say no."

"What are you talking about?" Klum demanded.

No matter, because the other two judges sided with the model, who gave him a "big, fat yes."

Tuesday's live auditions also featured Mandel hitting the all-important Golden Buzzer for 14-year-old Reid Wilson, who had come from Alabama to sing Lesley Gore's 1963 song "You Don't Own Me." While Wilson had appeared quiet and nervous, the voice that came out of him was big.

He won raves from all the judges, but Mandel was blown away, and used one of two Golden Buzzers he gets all season.

"Do you believe in dreams?" he asked the contestant. "Well, one of them is about to come true." 

After Mandel made his big move, he told Wilson that he did it because "your sound and who you are is nothing close to what I was expecting."

Live auditions continue for two more weeks, before the public voting begins.
