Tickling the ivories with a lively rendition of Chappell Roan’s hit Pink Pony Club at London’s St Pancras station last week, Myleene Klass entertained the throng of commuters as she joined the St John Ambulance campaign to teach more life-saving first aid.
Dressed in the charity’s distinctive green uniform, the musician and presenter beamed as her hands effortlessly danced over the piano keys.
But eagle-eyed onlookers might have noticed there was one thing missing on those elegant pianist’s fingers – her stunning, nine-carat diamond engagement ring.
Myleene’s fiance, the handsome and affable PR executive Simon Motson – with whom she has a six-year-old son Apollo – had presented her with the ring when he proposed during dinner in their north-west London garden in September 2020.
The thoughtful occasion involved Simon, 50, even sourcing the same table and chairs on which the couple had sat during their first date, five years previously, at Little House private members’ club in London’s Mayfair. The wedding has, however, failed to materialise.
Last night Myleene posted pictures on Instagram to promote her radio show on Smooth Radio and Classic FM that showed her wearing the ring.
But, intriguingly, it was the first time she had shown off that glittering rock on the page since May – when she posted images of herself in a floral gown on her way to the opera.

As for Simon, he has barely appeared at all in recent months, barring photographs in July of Myleene receiving her MBE from King Charles.
On recent trips to the South of France and Greece, which saw Myleene posing in a variety of bikinis, he didn’t appear – prompting speculation that he didn’t go with her.
The 47-year-old former Hear’Say singer, who rose to fame after appearing in ITV talent show Popstars in 2001, further failed to mention Simon at all during an interview with the Daily Mail last week, despite discussing her two older children Ava, 18, and Hero, 13, in great detail.
It is all, sources say, ‘a bit of a mystery’.
As one associate of the star tells me: ‘That engagement ring is beautiful, it’s massive, but why wouldn’t you wear it?
‘Myleene always seemed so happy with him, it all seems to be a bit of a mystery. Myleene has always been an open book, she did a big shoot with Hello magazine to reveal the engagement, she seemed so proud of her man.
‘Now, it’s like he doesn’t exist, like he has disappeared off the face of the Earth. She has stopped talking about him.’
Simon’s absence comes as Myleene is embroiled in a ‘whodunnit’ row she prompted in July when she revealed that she had caught her ex-husband Graham Quinn, the father of Ava and Hero, in a clinch with another female celebrity at her birthday party in 2011.
Speaking on Paul Brunson’s We Need To Talk podcast, she said:
‘I walked in on him with a famous person on my birthday on a balcony.’ She continued: ‘I’m in my house, it’s my party. They weren’t having sex, but they were unzipping each other. “It’s not what you think.” But I’m like, “It is what I think”.
‘It’s the first thing they both said. I kicked everyone out of the party, including his mum and dad. His dad said, “He doesn’t get it from me.” I remember thinking that was quite a weird thing to say.’
The revelations prompted a huge guessing game as fans tried to work out who the unnamed female, said to be known for her ‘family values’, could be.
Last weekend, I revealed that the woman in question has instructed lawyers to prevent Myleene from naming her by claiming that she is entitled to privacy.

Names that have wrongly been thrown into the ring have included Holly Willoughby, Stacey Solomon and Vogue Williams.
And while I know the identity of the celebrity, I cannot divulge it for legal reasons – yet.
Throughout all this, Simon’s low profile is perhaps understandable.
‘Imagine being that close to the whodunnit storm,’ says one source. ‘While there is so much sympathy for Myleene, she has dragged a lot of people into this. Would she really do that to Simon?’
I’m told that Simon’s old friends can’t help solve the mystery of why he – and the ring he bought her – has seemingly disappeared from Myleene’s public life, as they haven’t seen him for several years.
Some became estranged from him after he started dating Myleene in 2015, and in 2022 I revealed that some friends – and even some of his family – feared they would not be invited to the couple’s wedding, which was originally postponed due to Covid regulations.
At the time, sources close to the family said they felt they had ‘lost’ Simon but had retained hope of a reconciliation in the future.

But sources say Myleene has effectively done a ‘full-on Nicola Peltz’ – a pointed reference, of course, to claims that Brooklyn Beckham’s American wife Nicola is to blame for the wedge driven between Brooklyn and the rest of his family. One friend said at the time: ‘It is all very sad – families can be so complicated.
‘It looks unlikely that some of the members of his family will be there to see him marry Myleene, which would be a huge shame.
‘Some of those who have been closest to Simon for so many years feel like they have lost him.
‘There are desperate hopes that there can be some making up, but at the moment that doesn’t look that likely.’
Three years on and I’m told there has been no change. Simon is still estranged from those who were once his nearest and dearest.
One told me: ‘We haven’t spoken to Simon for years – it is sad.
‘Many of Simon’s friends are no fans of Myleene. We have lost contact with Simon since he has been with her. She seems to want him all to herself.’
As for a wedding, the last time Myleene discussed it was in October last year, when she blamed the family’s hectic schedule for the failure to pin down a date.
‘We have a lot of children between us, so at the minute it’s just one of those things that’s rumbling along,’ she said. ‘I reckon it will just happen.’ Only, as one source close to Myleene and Simon puts it: ‘He will have to come out of hiding first.’
