The mum-of-four, 35, shared a cosy photo at home with newborn Jett, eldest son Harvey, 11, and husband Kieran Hayler, 26. There's even a sleeping puppy in shot to complete the scene!
Katie gave birth to Jett Riviera on August 12 - eight weeks early by emergency caesarean - while on holiday in Europe.
Since coming home with her baby boy, she hasn't posted any pictures of the latest addition to her family - until now.
Katie can be seen cuddling up to son Harvey, who has little brother Jett on his lap. Kieran is sat next to them, smiling happily.
She captioned the photo: "'Aww me Jett @kieran0322 and my Harvs chillaxing."
Earlier this week, Katie showed off her post-baby body when she attended the Pure Beauty Awards.
She is also mum to Junior, eight, and Princess, six, her children with Peter Andre.
In a recent interview, Katie admitted she wants even more children!
