The Liberty X singer, 34, was at The Baby Show in Birmingham to meet fans and show off her new fitness DVD, Active Pregnancy.
Manning a stall at the NEC Birmingham, Michelle looked tanned, relaxed and happy in a bright yellow T-shirt worn with black tracksuit bottoms - perfect for her fitness demonstrations all day.
The DVD is aimed at pregnant women and contains three workouts for three different trimesters.
Fitness bunny Michelle also had a little helper on her exciting day - her two-year-old daughter Faith.
Alongside a cute picture of the toddler standing by Michelle's promotional posters, Michelle tweeted: "@hughhanley Faith loved been at work with @wonderwomanshel today... DVD is flying out #activepregnancy my baby girl."
A thrilled Michelle admitted she'd had a "fabulous time" at The Baby Show, while fans were quick to tweet their thanks to her after meeting her at the stall - which she manned all day.
One fan tweeted: "Great tips for exercising during pregnancy from @wonderwomanshel @TheBabyShow now!! Can't wait to try them at home!!"
It's been a rollercoaster year for Michelle and her husband, personal trainer Hugh Hanley, so far. They had their second child AJ in February, but were devastated when he was diagnosed with viral meningitis shortly after.
Now, although little AJ is on the mend, Michelle is raising awareness of the symptoms.
