The 37-year-old shared a photo of her chilling out with the kids today, and the all look like they're having a blast.
Alongside the snap Katie wrote: "Love Sunday's with the kids board games movies pizza delivery and cuddles [sic]."
Former glamour model Katie is mum to Harvey, 13, Junior, 10, Princess Tiaamii, eight, Jett Riviera, 23 months, and 11-month-old Bunny.
Husband Kieran Hayler, 28, is absent from the picture – but he's presumably the one taking it.
Katie recently admitted that she and personal trainer Kieran have relaxed their diets and they keep each other fit.
She told new! magazine: "The bedroom [keeps me slim]! We've got to keep each other on our toes.
"We have young kids and I've got a young lad… I'm not running around after the kids, I'm running around after him!"
Kieran added: "I've been there done it – the gym, the diet. I did it for six years and it took up my whole life."
