Less than three weeks since giving birth, Michelle, 34, looked stylish in a fitted turquoise jumpsuit, cinched at the waist with a purple belt.
She completed her look with an unusual pair of purple and red heels.
Michelle was at the photocall to accept the Disney Celebrity Mum of the Year Award. "Absolutely delighted," she later tweeted. "So so happy. Thank you everyone who voted xxxx."
Little Aaron Jay - or AJ, as he's nicknamed - wasn't with her at today's event, no doubt tucked up safe and warm at home with his dad, Michelle's personal trainer husband Hugh Hanley.
Liberty X and Big Reunion star Michelle gave birth to Aaron, her second child, on 28 February. She and Hugh are also parents to daughter Faith, who was born in January 2012.
Following Aaron's birth, a clearly thrilled Michelle took to Twitter to say she and Hugh were "so in love" with their little man.
"Thank you all so much for your well wishes.. Mine & @hughhanley little boy is snuggled into us and we are the happiness parents ever," she added.
"Thank u2 every1 at the knutsford suite #watfordhospital @WestHertsNHS & dr Sheridan 4 looking after us all. Time 2go home #familycomplete."
Michelle was diagnosed with having the BRCA2 gene in 2012. In November of the same year, she underwent a double mastectomy, as the gene can mean a high chance of developing breast and ovarian cancer. Michelle has also decided to have her ovaries removed.
She told Reveal in December: "No matter how daunting having my ovaries out is - and it is - it's necessary."
