The mother-of-five debuted her poker straight blonde hair on today's Loose Women, just a week after chopping her locks into a much shorter bob 'do.
So why the change?
She said: "I just feel sexier when it's longer."
Katie, 37, also joked that Taylor Swift, 26, had stolen her style, after the singer turned up to last night's Grammy Awards sporting a short, sharp bob of her own. "She phoned me and said, 'Can I use your hairdresser?'"
Katie's never afraid to switch up her style, changing the length of her hair and colour numerous times over the years. She's been blonde since 2014, when she cited Amanda Holden's tresses as an inspiration.
Meanwhile, the former glamour model has been nominated for the IceLolly Celebrity Mum of the Year Awards. She said this week: "Thrilled to have been nominated for the @icelollyholiday #CelebMumOfTheYear awards! Let's see me take home the crown."
Katie, who has three sons and two daughters, faces competition from the likes of Sam and Billie Faiers.
