The former glamour model was pictured make-up free, dressed in a black tracksuit with her hair tied back in a ponytail.
However, Katie's face looked noticeably puffy on one cheek with blotchy marks - leaving some fans to wonder if she had cosmetic treatment or an allergic reaction.
The mum-of-five was busy running errands in her hometown before appearing on ITV's This Morning last week.
However, Katie hit back at the speculation of any Botox, filler or cosmetic treatment as she took to Instagram to address her fans.
"Despite what people think I had done this day it was actually a sunbed," she wrote on the photo networking site.
Katie has been quite open in the past about getting Botox.
But last year, Katie made a new admission as she revealed on her FUBAR radio show that she doesn't want to go too far.
"Sometimes I've gone too far with it - my lips and my face - but I recognise that," she said. "You don't have Botox to look younger, it's just to refresh your face. A few years ago I think I went too far with the Botox, fillers and lips. I think I've eased off it now.
"When I look back at pictures I think, 'Oh my god!'"
