Heidi Klum, 51, is a busty bombshell in low-cut gray dress as she arrives at the America’s Got Talent quarterfinals

Heidi Klum looked blonde and sexy as she arrived at the live taping of America’s Got Talent in Pasadena, California on Tuesday night.

The 51-year-old German supermodel, who was spotted hours earlier in a lace bra, dazzled in a low-cut gray dress that showed off her ample cleavage.

The tight dress fell just above her ankles, allowing her to show off her black high heels.

Heidi’s sandy blonde hair fell in glamorous, loose curls over her chest.

As for makeup, the mother of four wore a sultry brown eyeshadow and her favorite glossy nude lipstick.

Her cheeks were flushed with a radiant peachy blush and her complexion had a distinctly sun-kissed glow.

Heidi was decked out in glittering jewelry, including a long gold chain and a chunky diamond bracelet.

Heidi exuded confidence and smiled for photographers as she walked the red carpet prior to the shoot.

She stopped to take pictures with 10-year-old singer Pranysqa Mishra, who is among the season’s quarter-finalists.

The 19th season of America’s Got Talent premiered in May 2024 on NBC.

Heidi serves as the competition judge alongside comedian Howie Mandel, Modern Family star Sofia Vergara and creator Simon Cowell.

Actor/comedian Terry Crews has been the show’s host since 2019.

Tuesday night’s episode marked the final round of the quarter-finals, which kicked off on August 14 after eight rounds of auditions.

For the first time in AGT history, the judges were given a live show golden buzzer. When pressed, the live golden buzzer will send one lucky act straight to the show’s finale.

And the judges seemed very happy to have completed this phase of the competition, posing on the red carpet before the show.

Howie looked chic in a fitted jacket, skinny pants and crisp white loafers.

The 68-year-old stand-up comedian completed his outfit with designer sunglasses.

Simon, 64, made it a family affair by walking the red carpet with his son Eric Cowell, 10, and his fiancée Lauren Silverman, 47.

Sofia didn’t appear on the red carpet, but she did later appear in a sexy orange strapless dress with the judges.

Presenter Terry showed off his muscular physique in a fitted green suit with matching tie and a crisp white shirt.

E! News correspondent Catt Sadler was also in attendance at the celebratory evening in LA.

The 50-year-old reporter looked effortlessly stylish in brown satin trousers and a low-cut blouse as she surrounded herself with Simon’s fiancé.

Before Heidi appeared in front of the cameras in her fuller dress, she showed off her Instagram Story getting ready.

She photographed her hairdresser putting the finishing touches on her blonde curls as she sat patiently in a chair.

Pieces of hair were secured with bright pink clips, creating a flattering curl pattern around her face.

Heidi posted a close-up selfie, giving her 12.2 million followers a better look at her flawless makeup.
