Amanda Holden, 52, makes a VERY racy appearance in a cutout dress as she arrives at Global’s star-studded Make Some Noise charity gala

Amanda Holden is not afraid to appear in trendy outfits.

And on Tuesday, the 52-year-old BGT judge appeared wearing little to nothing at Global Radio’s Make Some Noise charity gala at London’s Leicester Square Hotel.

The Heart FM breakfast radio presenter showed off her daring look on Instagram in a series of snaps in which she flashed a glimpse of her underwear in a semi-sheer dress.

She slipped into a sexy long-sleeve ensemble and opted to unzip it – to show off her ample cleavage.

Her unusually fitted, detailed, racy necklines reveal her hips, legs and torso, while her black lingerie is visible through the garment.

Earlier in the day, Amanda went braless as she showed off her stylish look while working at the Heart FM studios.

The gala event will raise money for Global’s Make Some Noise charity, helping disadvantaged children, young people and their families across the UK.

Earlier this month, Amanda undertook many grueling challenges to raise money for the charity.

The presenter really championed the cause as she also jumped 13,000 feet out of a plane and climbed the Blackpool Tower while presenting her breakfast show.

For five days in a row, Amanda and her co-host Ashley Roberts took on five challenges for the charity The Heart – called Race Against Time.

As if things couldn’t get any more strenuous, the duo only had an hour to complete each challenge, which also included traveling across the Thames in a yellow kayak.

I also joined the Wings Parachute Display Team on the tandem jump, which specializes in epic aerial displays – and Amanda’s was just as mesmerizing.

In the first challenge, Amanda climbed to the top of the tower and became the first person ever to win the title.
