The mum-to-be was pictured in an all-grey ensemble, including a scarf which she used to obscure her midriff. She also carried a huge brown leather handbag – another celebrity trick to hide that baby bump!
Katie, 35, is expecting her fourth child later this year. It will be her first with third husband Kieran Hayler, 26, who she married in The Bahamas in January after a whirlwind romance.
The model, who is also mum to sons Harvey and Junior, and daughter Princess, hasn't let her pregnancy slow down her work schedule, and has been doing the publicity rounds lately for her latest book, He's The One. It's her 49th book, if you can believe it!
In addition to promoting her book and preparing for her new arrival, the star has been teasing fans about the launch of her latest perfume, named Kissable, and also found time to serve as special guest at The Sunday Times Festival of Education at Wellington College.
Katie spoke at the prestigious college last week about life with her 11-year-old son Harvey, who has special needs.
