AGT's Heidi Klum risks wardrobe malfunction in tiniest red dress as she dances seductively on first night of live shows

HEIDI Klum has almost shown off a little too much in a new dancing video.

The America's Got Talent star posted an Instagram clip from behind the scenes of the first round of live shows on Tuesday.

In the video, Heidi, 50, was filmed as she performed a raunchy routine backstage before the show.

For the night's show, Heidi wore a teeny red dress, which reached just under her butt.

The tight fabric clung to the model's body, and had two peepholes over her chest and ribcage.

The plunging neckline was held up by two thin straps, with Heidi's cleavage on full display as she bent over while pouting.

Heidi wore her blond hair down in choppy layers, and tousled it as she ran her hands through the locks while gyrating her hips.

The star wore a full face of makeup for her TV appearance, with plenty of mascara and nude lipstick.

At the end of the video, Heidi turned her back on the camera and pushed out her butt while running her hands over her curves.

She pulled up the hem of her dress with her long red nails, pulling the fabric high enough to show off her bare butt.

The German-born star captioned the clip with a long line of red hearts and an emoji sticking its tongue out.

Heidi married Tokio Hotel frontman Tom Kaulitz, 33 in 2019.

Over the weekend, Heidi opened up about her age difference with Tom on her Instagram Stories.

During a Q&A, one fan asked: "Don't you feel that you're in the age of Tom's mom or age really doesn't matter?"

Heidi sassily responded: "I honestly only feel that way when people point it out to me."

Prior to her current romance, the famous model was married to British singer Seal, 60, for nine years.

The couple had three children together, with Seal also adopting Heidi's daughter Leni, who was born from a prior relationship.

Heidi and Seal's marriage crumbled in 2012 after the singer accused her of cheating on him with one of their security guards.

At the height of their bitter custody battle, Seal claimed his ex-wife's "hidden agenda" was to move their children to Germany permanently.

Earlier this month, AGT fans took to Reddit to comment on a habit that they want the judges to stop doing during the live shows, which began yesterday.

The original poster wrote: "Judges interrupting acts with their opinions and X's during the Live shows when it is up to the public to decide who advances. Why do they try to influence the vote?"

Other fans chimed in and agreed that they wanted the judges to stop their interruptions.

"I agree. I find it rude. Especially when the crowd boos too. It's rude," said one Reddit user.

"Guess they just want to show that they are not completely useless in the live shows and that they do deserve the millions they get for being there," one fan replied.

Another social media user pointed out: "If they are doing terrible in the live shows that indicates that judges/producers have failed. These are the last 55 remaining selected acts of more than ten thousand."

The original poster replied: "Exactly! If they need to get buzzed during the Lives [then] either the producers or judges or all screwed up."
