Katie, 35, is rubbing noses with her 25-year-old hubby in the photograph and looks blissfully relaxed as they share a joke together in the kitchen at home.
The mum-of-four, who is also make-up free in the snap, posted it on Twitter alongside a sweet message for Kieran, who she married in January last year.
Katie said: "@kieran0322 you make me so happy, you make me laugh all the time xxx." Aww!
After tying the knot in the Bahamas following a whirlwind romance, Katie and Kieran welcomed their first baby together, Jett Riviera, into the world in September.
Meanwhile, Katie has been out and about in the countryside doing what she loves best - horse riding.
The former glamour model is a keen horsewoman and has also tweeted a picture of herself while riding her handsome horse Wallis.
Messaging a friend, she said: "Thank you for grooming Wallis and getting him ready for my show xx."
