The Liberty X star asked her Twitter followers: "Any1 just had a baby .. Thinks while looking down at her belly "wow.. looks like they left one in there"? anyone? ... Nope? Just me then lol."
Michelle's been at home looking after her brand new baby boy, as well as daughter Faith and hubby Hugh Hanley, ever since she came out of hospital on Sunday (2 March).
Like most new mums, she's also getting to grips with her post-pregnancy figure.
The fitness fan incorporated some exercise into her pregnancy and, now that she's given birth, she's taking steps to make sure she's eating a healthy diet.
Michelle posted a photo of a tasty-looking banana yoghurt with cocoa granola pot on Monday.
She added: "Day 1 #soulmatefood @Soulmatefood @ChristianCoates yummy!"
However, Michelle's family will always be at the front of her mind.
On February 28, the very same day her son was born, she Tweeted: "Thank you all so much for your well wishes.. Mine & @hughhanley little boy is snuggled into us and we are the happiness parents ever.. Xx."
And more recently, she added: "Thank u2 every1 at the knutsford suite #watfordhospital @WestHertsNHS & dr Sheridan 4 looking after us all. Time 2go home #familycomplete."
