The businesswoman, 35, posted the adorable snaps on Twitter, showing the family having a great time on the beach.
In the pictures, Katie, husband Kieran Hayler, 29, eight-year-old son Junior and daughter Princess Tiaamii, 8, are enjoying the sandy beach and beautiful sea together.
Katie’s other children, 12-year-old Harvey and 7-month-old Jett Riviera are absent from the beach pictures.
Former model Katie looked relaxed and happy as she posed in the sea with Princess, and she and Kieran looked very much in love as they kissed while laying on the sand.
She also took the chance to show off both of their wedding rings, posting a picture along with the caption: “Comparing tans on Tortuga Beach”
Hubby Kieran also took to Twitter to post a cute snap of Jett, writing: “Me and Jett watching the divers feed the fish in the amazing Cape Verde!!!!! Such a good day!!!”
Meanwhile, Katie recently spoke out about her desire to have more children. In her magazine column, she revealed: “I would love another baby, possible a few more, but I will do so when I’m ready. And I’m not ready yet.
“So less of the speculation and rumours, people! If and when I do have baby news, I’ll tell Now readers – not one of these imaginary friends or sources.”
