The singer, 35, attended the premiere of TV show Dora And Friends: Into The City with hubby Hugh Hanley and their two children, two-year-old Faith, and AJ, eight months.
Wearing a striking red dress and black tights combo, Michelle looked simply stunning - and her kids looked pretty cute, too!
Before heading to the London event, Michelle posted her own snap of her adorable family at home.
She wrote: "Getting family ready for @nickjruk #DoraAndFriends premier - Faith obv excited ..Think @hughhanley may be too! Lol."
It's heart-warming to see the Heaton-Hanley clan looking so happy after a difficult few months, including AJ battling viral meningitis and Michelle's painful decision to undergo a full hysterectomy.
And Michelle wasn't the only stunning mummy at the Nickelodeon premiere...
Former Miss Wales Imogen Thomas also attended the kiddie event with her daughter Ariana.
After the fun afternoon, Imogen tweeted: "We had the most amazing time @NickJrUK Dora and friends into the city. Thank u so much for your generous goody bag too.
