The 37-year-old took to Instagram to debut her new look, flashing her honey-blonde tresses.
“Never expected to go blonde so quickly and keeping my hair healthy from going dark to blonde huge thanks to @colourb4 and @itsdash [sic],” she wrote.
Katie’s followers were quick to compliment her on the new style, with one writing: “Your hair looks lovely this colour x [sic]” Another said: “Wow best I’ve seen it!”
“Didn’t even recognise u. Still beautiful thou,” one user gushed.
But one eagled-eyed follower pointed out there could be a message behind Katie’s sudden change from dark to light.
They wrote: “Ru preggers as u always go blonde when your preggers! Lovely tho! Blondes have way more fun! [sic]”
Pregnant or not, there’s no denying Katie looks sensational. It’s been reported for a few weeks now that she could be pregnant with her sixth child, and she took to Instagram last week to comment on the news.
Not confirming or denying the reports, the former glamour model posted a snap of her with a cushion up her top and wrote: “According to the mags I have tumthing to tell [sic]”
