Katie, 35, unveiled her latest hair 'do today (18 February) by sweeping her short style to the side for a selfie.
Uploading the snap to Twitter, Katie told her followers: "Short hair we go lol."
In the past, the mum-of-four has tended to opt for long flowing extensions - sometimes with them reaching as far as her waist.
However, earlier this month, Katie showed off a shorter style at the RoboCop premiere in London.
It seems she's now a fan of easy-care hair, as this latest style could be the shortest we've seen on Katie...EVER!
