Myleene Klass puts on a leggy display as she showcases her musical abilities with piano performance at Global’s Make Some Noise charity gala

Myleene Klass put on a leggy show on Tuesday night as she attended Global Radio’s star-studded Make Some Noise charity gala.

The former Hear’Say singer, 45, demonstrated her piano skills as she took to the stage at The Londoner Hotel in Leicester Square.

Myleene looked stunning for the event as she donned a daring blue sleeveless dress with a plunging neckline.

The revealing garment also featured a slit at the legs, which helped to highlight the star’s incredible figure.

Myleene let her brunette locks fall loose over her shoulders and also wore a pair of chunky silver heels as she took to the stage.

Her impeccable performance proved to be a hit as a video posted to her Instagram Stories showed the room erupting with applause and ‘screeching’ sounds.

Myleene started out as a music teacher 20 years ago before becoming a TV presenter and singer.

She rose to fame on the TV talent show Popstars with Kym Marsh in 2001 before releasing two classic solo albums in 2003 and 2007.

Since then she has hosted Smooth Radio and has a weekend slot on Classic FM.

Her plus one for the evening was her fiancé Simon Motson as they arrived hand in hand as they entered the event.

PR director Simon looked incredibly dapper in a chic green velvet suit jacket tuxedo and looked smitten with Myleene.

The Gala event raises money for Global’s Make Some Noise charity to help disadvantaged children, young people and their families in the UK.

Earlier this month, Amanda Holden and Ashley Roberts undertook many grueling challenges in a bid to raise money for charity.

Daring: Myleene made sure she turned heads in the sheer garment as she showed off her lingerie in the eye-catching outfit

The presenter really proved herself for the cause when she also jumped 4,000 meters out of a plane and climbed Blackpool Tower while presenting her breakfast show.

Five days in a row, Amanda and her co-host Ashley faced five challenges for The Heart charity called Race Against Time.

As if things couldn’t get any tougher, the duo had just one hour to complete each challenge, which also involved navigating the Thames in a yellow kayak.

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

Stunning: Her outfit was completed with dangling earrings and a simple silver bracelet, which she pulled from a bag

In the first challenge, Amanda climbed to the top of the tower and claimed the title as the first person to ever do so.

The daredevil managed to reach all the way to the top and hit the flagpole in an impressive 57 minutes and 59 seconds.

Amanda, Ashley and Jamie Theakston are celebrating ten years of changing lives by supporting small projects across the UK, including in the areas of mental health, food poverty, domestic abuse, homelessness and loneliness.
