Myleene Klass is a ray of sunshine in a bright yellow plunging maxi-dress on hottest day of the year

She’s been sending temperatures soaring in the style stakes throughout this week’s sweltering summer heatwave.

And Myleene Klass was a ray of sunshine as she made another glamorous arrival at the Global studios in central London on Thursday morning to present her Smooth Radio show.

The broadcaster, 42, battled scorching 34C heat on the hottest day of the year as she slipped into a bright yellow plunging maxi-dress with a pretty paisley pattern.

The TV and radio host injected a touch of designer glamour with the addition of a black quilted leather bag from her vast Chanel collection.

The mother-of-three kept cool in a pair of raffia wedge sandals, while sheltering her eyes from the summer sunshine with a pair of gold-rimmed shades.

The former pop star wore her chestnut locks in loose waves and opted for minimal makeup to accentuate her naturally beautiful looks as she arrived at the studios with a huge grin on her face.

The presenter recently revealed she would like to have another baby and hopes to marry her businessman boyfriend of five years, Simon Motson, 45, in 2021. 

She has two daughters, Ava, 12, and Hero, nine, from her previous marriage, while Simon has a son and daughter the same age as Myleene’s girls with his ex-wife.

The couple are parents to a son, Apollo, 10 months, together, who Myleene has previously described as their ‘miracle’ baby. 

Speaking in an interview with Hello! magazine earlier this month, she said: ‘I would not say no to another baby. I don’t want to tempt fate. Who knows what life has got planned for you?

‘We didn’t know we would even get him [Apollo]. The kids would love it if we had another baby. Simon is raring to go.’

Myleene also joked that her girls have been ‘on Simon’s case’ to propose and said they’ve already got the nuptials ‘all planned out’.

She added: ‘My girls are definitely on Sim’s case about it [marriage]. I suppose it’s just children’s way of solidifying what’s around them. The kids just want a party. 

‘Sim doesn’t get a say in it either. It’s genuinely down to the children. They’ve got their own conflab going on between them and have planned it all out.

‘They have even decided the baby will be the ring bearer! There are no weddings this year. But 2021? They would love that!’ 

Myleene paid a sweet tribute to Simon on Sunday for Father’s Day and said their ‘blended family of seven’ are ‘so lucky’ to have him.

Alongside a sweet photograph of Simon and a newborn Apollo, she wrote: ‘Happy Father’s Day to this incredible man. Who knew five years ago we’d be a blended family of 7?! I mean! 5 children, yet you take it all in your stride! 

‘The multiple school drop offs, Michelin star cooking, terrible movie suggestions, DIY, sports tips, French lessons, homework, more homework, Baby Olympics training, the hugs, the love, the everything. 

‘Always laughing. Thank you for all of it. We are all so lucky to have you. In Ava’s words, it takes more than DNA to be a dad, It’s takes YOU.’ 

The classically-trained musician was previously married to Graham Quinn, but the celebrity bodyguard left her heartbroken when he walked out of the family home on her 34th birthday in April 2012.

The incident came just six months after the couple’s wedding, but they had been together for 11 years at the time, after meeting when Graham became the bodyguard for Myleene’s pop group Hear’Say in 2001.
