The TV presenter, charity worker and mum-of-one proved that there isn't a look she can't pull off as she cut the ribbon in this seriously snappy two-piece by Genese London, that boasted a velvet blue blazer complete with silky lapels and matching cigarette trousers which accentuated her teeny tiny (and very enviable) figure.
The ultimate Xmas party look? We think so!
Katie teamed her ultra-stylish suit with a simple, button-up black top and co-ordinating pointed toe court heels, but it was her stunning make-up a la Ex On The Beach's Charlotte Dawson that really stole the show.
Katie usually keeps things neutral when it comes to dressing her face, but she ditched the failsafe black kohl and bronze eyeshadows for a swipe of electric blue liner which accentuated her pretty peepers and offset her suit perfectly.
The Bodyshockers star was all smiles as she posed for the paparazzi, greeted fans and signed copies of her book, Beautiful Ever After.
Katie has been a super busy bee lately and recently launched her very own range of buggies and travel sets with My Babiie.
Talking to Reveal, Katie gushed about the collection and revealed that she took inspiration from her very own wardrobe!
"I actually designed the buggies with my clothes in mind!" Katie said.
"Each one is inspired by colours and shades I really like wearing because I think it's really important not to loose yourself when you become a parent. I didn't want a buggy with Fireman Sam on because I don't wear dresses with Fireman Sam on [laughs] but because I'd been a mum and tried and tested it all on myself and Belle I didn't compromise on the safety aspect."
She went on to say, "This is the first time I've ever done something like this but they let me bring my ethos and my mantras on board. It's reminiscent of the way I live my life through my charity and all of the books I write.
"The whole idea about calling it Believe Buggies goes back to that idea of having self esteem and belief in yourself as an individual as well as a parent. When you've got those two things, you've got confidence and when you have that, you can do absolutely anything.
