The mother-of-four unveiled her sophisticated hairdo while on a photoshoot on Thursday (13 March) ... though remained the same cheeky Katie by pulling a sultry pout.
Katie added the caption: "First sexy shoot with short hair and my own hair wooo."
We already knew Katie - aka Jordan - had chopped her natural hair into a shorter style, as back in February she uploaded a picture to Twitter showing her cropped locks.
But this is the first time we've seen her all dolled up. And, after her excursion to Cheltenham Festival this week, we had been wondering if she'd put the extensions back in...
Katie gave fans before and after images from her "sexy" shoot, but no details about what she was actually filming for.
The 35-year-old was last seen with a long ponytail while attending the opening day of Cheltenham Festival with her husband Kieran Hayler on 11 March.
Long hair one day, short the next. We can't keep up!
