Heidi Klum, 49, wows in bustier and hot pants as she heads to film America’s Got Talent in LA

MODEL Heidi Klum buckles down to work in a belter of a bustier and seriously hot pants.

She was in LA heading to film America’s Got Talent, on which she is a judge.

The mum of four, 49, told last week how proud she was of daughter Leni, 18, going to college in New York.

Heidi added: “It’s not modelling and she’s really excited.”

This comes weeks after Heidi shut DOWN costar Simon Cowell during an episode of America's Got Talent after he made cruel comments about a fan-favorite singer.

During the final week of America’s Got Talent auditions, a contestant named Freckled Zelda wowed the audience and judges alike when she turned up dressed as a full-on fairy.

She had even bought along a “potato” flute and a pair of elf-ears to complete the look.

“I’m a music fairy,” she told the judges, who looked on curiously.

“Really?” asked a skeptical Simon, 62.

However, once Freckled Zelda began to sing her cover of Colors of the Wind, she exceeded all the judges’ expectations with her powerful voice.

After receiving a huge round of applause for her impressive performance, the musical fairy burst into tears.

She then nervously awaited the judges’ feedback.

Simon was characteristically honest as he said: “I tell you what, when you walked out, I thought, 'This really is going to be terrible,' - I did.”

As the audience booed, he added: “But actually you’ve got a really good voice.

“I don’t like the instrument, don’t think it’s necessary. Carry on looking like that if you want, because you’re interesting.”

Heidi told Freckled Zelda: “You nailed that - I loved it.”

As the model took a deeper dig at her fellow judge, she added: “America’s Got Talent is a variety show, and we don’t all have to be the same.”
