Competing already? America's Got Talent newcomer Heidi Klum upstages fellow judge Mel B as she slips into a tight strapless dress for NBC event

Heidi Klum was proud of her new judging post on America's Got Talent and her cleavage on Monday night.
The supermodel may have had upstaging in mind when she walked the red carpet at the NBC Universal Summer Press Day in a sexy black number with sparkly accents.
Heidi was tan and radiant as she preened and posed in her strappy black heels, showing off her amazing figure at every possible angle.

She's a stunner: Heidi Klum paraded her physical assets in a tight strapless dress as she hit up the NBC Universal Summer Press Tour in Pasadena on Monday

The 39-year-old mother-of-four wore her golden-kissed tresses loose and parted in the middle as she glided to the venue being held at Langham Huntington Hotel & Spa in Pasadena, California.
Heidi is obviously overjoyed with her new role as judge on the competition show and that wide smile said it all.
Earlier in the day, Heidi was seen arriving to the hotel in a billowy black and white maxi-length dress and chic black flip flops.
The Sports Illustrated Swimsuit model held a large bottled water to stay hydrated in the warm 80-degree weather.

Heidi also had a wrap wedged into her big black tote for when it got cooler later.
She no doubt intended to make the most of her day in the spotlight.
Fellow AGT judge Mel B, on the other hand, turned heads too by squeezing her curvy figure into a black short-sleeved frock with a center panel of black and white stripes.
The hemline stopped at her knees and allowed a view of her toned calves and trim ankles, as well as her pointy chrome high heels.

Former Victoria's Secret Angel certainly has the experience for AGT, having already made an impact on Project Runway.
NBC made the announcement on March 4 that Heidi would be added as a fourth judge to the show.
The move could definitely cause some friction in months to come as Mel B and Heidi are both strong opinionated ladies.

It means that Klum will be rubbing elbows with fellow judge Mel B as well as returning judges Howie Mandel and Howard Stern beginning this summer.
