She has launched online music classes as she and her family join millions of Brits in lockdown amid the coronavirus pandemic.
And Myleene Klass joked that she may end up with a fourth baby during the period of self isolation in a candid chat with The Sun.
The presenter, 41, who vowed to have no more kids after third child Apollo arrived in August 2019, joked that extended periods of time at home with partner Simon Motson could lead to a new arrival or a divorce.

She said: 'There's either going to be a divorce boom or a baby boom — and I've got a good midwife and lawyers for either.'
The former Hear'Say singer, who is also mum to daughters Ava, 12 and Hero, nine, credits ironing and playing the piano with losing three of the five stone she gained during her pregnancy with Apollo.
'I've still got two stone to go. I don't know if the lock-in is going to help that. We'll just do the best we can.
'I go about my daily life, but you don't realise...I found out that ironing burns a lot of calories and playing the piano, it's like being an athlete,' she said.

While Myleene's daughters have followed in her piano playing footsteps, she has high hopes Apollo will be as musically minded, dubbing him the next Elton John.
Myleene also cheekily revealed partner Simon had been a campanologist (bell ringer) at school and played the clarinet.
It comes after Myleene revealed her grand plans to become 'the nation's music teacher' during the COVID-19 lockdown.
The mother of three and former Hear'Say singer had a brainwave last week as the UK prepared to go into lockdown, realising she can offer her talents as a classically trained musician.
After discussing the stresses of homeschooling in her school mums Whatsapp group, Myleene has decided to do her bit to ease the burden on parents by launching her online music lessons, dubbed Music Klass.

She tried out the classes last week, taking requests from her 300k Instagram followers as she played tune after tune at her home piano.
Her daughters Ava, 12, and Hero, eight, joined in, wowing with their talents after years of being taught by their mum, while baby Apollo, seven months, sat on laps and her boyfriend Simon Motson played cameraman.
'When I was a poor student working in a bar that's what I'd do, I'd sit there and play whatever,' she says, 'playing by ear has been my hidden secret that no one has ever really known that I can do!'
This week, the Music Klass plan has evolved to include two classes for the whole family on Monday and Fridays at 10am, plus a lullaby session on Wednesday evenings where the talented star will serenade us all by taking requests, this week's theme is Disney.

Speaking to MailOnline about her new initiative, Myleene admitted she started out doing the videos for her mum friends.
'I have a Whatsapp group with a load of my school mum friends. All of us are having a meltdown about home schooling and homework,' she admits. 'And I just said 'I'm teaching my children music at home anyway so I'm just going to turn the whole thing into a lesson and you can have it for free, it's my gift!''
Myleene, like most parents, admits home schooling 'is a really big ask on a lot of families,' after schools and nurseries were closed to all but the children of key workers from Monday.
'We need a break,' she insists, 'we're trying to work from home, trying to keep the
