Myleene Klass shows off her long legs as she shows off her musical prowess with a piano performance at Global’s Make Some Noise charity gala

Myleene Klass showed off her leggy looks as she attended Global Radio’s star-studded Make Some Noise charity gala on Tuesday night.

The former Hear’Say singer, 45, showed off her piano skills as she took to the stage at London’s Leicester Square Hotel.

Myleene looked incredible for the event as she slipped into a daring blue sleeveless dress with a plunging neckline.

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

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

Her flawless performance proved to be a success as a video posted to her Instagram Stories showed the room erupting in applause and cheers.

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

She rose to fame in 2001 on the TV talent show Popstars with Kym Marsh 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 bright spot on the night was her fiancé Simon Motson as they arrived holding hands on the way to the event.

PR manager Simon looked incredibly dapper in a sleek green velor tuxedo and seemed smitten with Myleene.

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 Holden and Ashley Roberts faced 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 took on five challenges for 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.

The daredevil managed to reach the top and touch 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 violence, homelessness and loneliness.
