Simon Cowell cut a casual figure in a grey T-shirt and black trousers at the America’s Got Talent season 19 quarterfinals at Hotel Dena on Tuesday night.
The music mogul, 64, seemed in good spirits as he crossed his arms while posing for photos on the red carpet ahead of filming the TV show which airs on NBC.
Simon completed his dark comfortable outfit with a pair of eye catching red tinted glasses which help prevent migraines.
Meanwhile Heidi Klum turned heads as she went braless under a brown unbuttoned shirt which she tied at the front. 
The supermodel, 51, looked incredible as she put on a leggy display in a matching puff miniskirt and towering stilettos heels.
Leaving her long blonde locks loose, the judge accessorised with a dazzling silver drop necklace and matching rings.
Heidi flashed her gorgeous smile while posing for cameras and completed her ensemble with a bold red manicure.
The duo were also seen posing alongside fellow judge Howie Mandel, who dressed smart in a navy blazer for the evening.
During the show, Simon reached over and tried to push Howie’s Golden Buzzer for Airfootworks from Japan on Tuesday.
‘I am just about to get myself fired,’ Simon said, while reaching over and attempting to push the Golden Buzzer that belonged to Howie for the episode.
The crowd cheered for the group of hip hop dancers and break dancers who had shown off their unique style of dance to the world. The four person trio all dressed in white danced while hanging onto a bar and holding themselves up and kicking their feet into the air. Howie rushed to the stage.
‘Okay I’ve got to clear this up Howie got there first, this is Howie’s Golden Buzzer,’ Host Terry Crews, 55, said.
Simon then rushed to the stage and Howie tried to block him.
‘Simon wants to take the credit,’ Terry said. ‘Howie this is your Golden Buzzer. ‘
‘This is mine,’ Howie said while watching Simon on stage congratulating the dancers.
Terry later played the replay that showed both Simon and Howie reaching for the Golden Buzzer at the same time. The replay showed that Howie actually hit the buzzer first.
‘I feel like I’ve been abused,’ Howie said.
‘Look, I think when you watch the tape back you will find my finger got there just before Howie,’ Simon said.
‘Well keep your fingers off of my buzzer,’ Howie said.
Terry said because of the Golden Buzzer that AirFootworks will go straight to the finals.
Legión, a dance group from Buenos Aires, Argentina, performed with their boots on fire to open the second live quarterfinals.
Sofia Vergara, 52, had given them the Golden Buzzer earlier in the season, sending them straight to the live show. They danced and drummed while their boots were engulfed in flames and later their hats, too.
‘Sofia your Golden Buzzer winner, was on fire!’ Terry said.
Simon wasn’t impressed.
‘It wasn’t as good as I thought it was going to be,’ Simon said. ‘I don’t know what it was. I just wanted more.’
