Myleene Klass looks glamorous in a lime green maxi dress as she hosts the classical concert at BST Hyde Park

Myleene Klass exuded glamour in a lime green maxi dress as she hosted the biggest classical concert in Hyde Park on Friday.

The 46-year-old presenter looked stunning in the plunging number with a cutout at the front and a pleated tie that accentuated her waist and showed off her enviable figure.

Myleene brought the glam to the stage as she stepped out to introduce the Royal Philharmonic Concert Orchestra during British Summertime in a pair of chunky gold platform heels.

The I’m A Celebrity star accessorized with a pair of hoop earrings and beaded bracelets.

Myleene, who had attended the Girl Aloud concert the night before, completed her striking outfit with a smokey eye palette and styled her long brunette locks in a side braid.

On her Instagram, Myleene shared some behind-the-scenes stories about what was going on in the run-up to the concert, including two set up dining tables behind the stage curtain so the orchestra could ‘grab a cup of tea during the break’.

She revealed that the first piece they would perform was Star Wars and then let her followers inside her very chic trailer.

Myleene called it the ‘Winnebago’ and joked that it was bigger than her apartment as it came with a breakfast bar, a leather three-piece suite, a kitchen with a fully functioning oven, a large double bed and a shower.

The outing comes at a time when Myleene talks about turning to her teenage daughters when she’s having a hard time and wants a laugh.

The former Hear’Say singer, 46, has daughters Ava, 16, and Hero, 13, with ex-husband Graham Quinn, and explains that she thinks it’s “amazing” that her children are so knowledgeable about their mental health.

She told MailOnline: ‘When things get over my head I have to show my daughters why I feel this way.

‘They are so incredibly involved in mental health and that’s great to see.

“I think they just know that they have to show how they feel and they are very committed to what they have to do.”

The TV personality, who is engaged to Simon Motson and has son Apollo, four with him, returned to her place on the Loose Women panel earlier this year after more than a decade.

She explained that so much has happened to her during the ITV show that she feels like both she and the audience have grown since her first stint.

She added: ‘The last time I was there I didn’t have a son. I didn’t have a fiancé, and I think with all the changes in my life – I have two teenagers now – I have different things to draw on.

‘I also have different experiences myself. It is a very interesting program, because it absolutely grows with you and you also grow with the viewers.’
