The pregnant model gave us a close up look of her new look via her YouGossip channel at the weekend, looking very sultry in the after shot - and we think she looks amazing!
Katie's new look came courtesy of Beauty Works extensions and hairstylist Seaane Chine-Hoyte. She tweeted: "Love my new hair weave from @beauty_works done by @hairbyseaane so quick and easy."
Seaane also tended to Katie's tresses before her appearance on Loose Women on Friday, where she was rocking a gorgeous, shiny blow dry.
We have to say, we really love this colour on Katie. Very natural and totally fab for summer.
Katie, of course, has tried every colour and style under the sun, most recently showing off insanely multi-coloured locks (courtesy of a wig!) at the launch of her Colour B4 partnership earlier this month.
The 36-year-old actually told Reveal this month that she was all about elegant blonde at the minute, citing Amanda Holden as a hair inspiration.
She also admitted – like many of us – that she's had a few dodgy styles in the past…
"When I want to go blonde I always get the wrong blonde, I've never had one I like. Then when I look at pictures of myself, I like my hair dark, but when I had it dark last time I was pregnant, I didn't like it. I just don't know what I like at the moment.
"There's lots of times I've been unhappy with my colour, and that's why my hair got wrecked, because I wanted to change it all the time and it broke off."
We think it looks fab and healthy right now, Katie.
