Donning skintight leathers and a sassy pair of over-the-knee boots, Katie made sure to turn heads as she spread the word about her latest book.
Spotted heading into BBC Radio 2 earlier this morning, former model Katie looked effortlessly glamorous for her promo trip in the capital.
The mum-of-five teamed a fun-loving, heart-printed blouse with a pair of spray-on leather trousers and gorgeous suede over-the-knee boots.
On the beauty front, Katie showed off her newly-darkened locks, sporting a perfect blow-dry as she let her glossy mane fall past her shoulders.
For her make-up, the 36-year-old kept things simple with blusher-tinted cheekbones, fluttery long lashes and a light pink gloss on her lips.
Last week, at the launch of her latest novel, Katie told Reveal that after putting together her books, her storylines always come true.
Make My Wish Come True tells the story of an undercover journalist, Storm, in a plot filled with love, sex, scandal and betrayal.
Speaking about her latest release, Katie said: "When I come up with the plots for my books, there are always some things that actually come true afterwards."
She added: "It's really weird. There's betrayal between friends, that's happened to me. Then there's betrayal with the character's boyfriend, that's also happened to me!"
But not only does the recent drama in her life reflect the events of her new book, Katie revealed she actually has the same hair and eye colour as her main character too.
Sounds like the resemblance is uncanny...
Meanwhile, Katie also revealed she has already started writing her next tell-all autobiography.
After finding out while pregnant that her husband Kieran Hayler had been having an affair, Katie has promised to pen all about her difficult year and much more in her next book.
Hinting a lot has gone on behind-the-scenes that people don't know about, Katie tells us "all will soon be explained".
Intrigued? Us too!
Since announcing her autobiography plans, Katie has gone on to say that she is glad Kieran cheated on her with two of her friends.
Making the controversial claims during an appearance on Loose Women last week, she said: "I am so pleased he did it with two of my friends.
"If it was just one he would have been focused on her. The fact that he did it with another one... It was meaningless."
