But the 37-year-old was met with backlash after sharing a snap of her trim figure this week, with some of her followers branding her a bad role model for young girls.
“Why would anyone want to look like that?” One user asked. “It’s not healthy and looks horrid! [sic].”
Another said: “More ribs than boobs? Not really nice to look at, kinda pro anorexia [sic].”
But Katie wasn’t going to be shamed. She hit back: “I’m not perfect and not trying to be it just seems WHATEVER I do people will always pick holes in me but I’m used to it now [sic].
“Pick holes in my body all you like but I know I’m very lucky to have a body like this after five children and can only thank my mum and dad’s genes but I’m sure if any of you pose in a bikini you’re not going to breathe right out [sic].”
Despite the many negative comments, Katie’s post was praised by some who shared their envy over her body.
One gushed: “Wow what a body! You look amazing. I have one child and I’m struggling to lose weight [sic].”
Another added: “You look wicked. Not many ladies have a banging figure like yours after 5 kids. Then again even ladies that don’t have kids don’t have a fit body… so let the HATERS HATE AS THERE ONLY JEALOUS OD WHAT THEY COULD NEVER BE [sic].”
