The ex-glamour model and mum-of-four uploaded the picture on Sunday night (2 March) after a home tanning session and was clearly so proud of her efforts that she needed to share the results immediately.
She tweeted: "Thought I'd show how brown and even my tan is ;) thanks @kieran0322 for taking pic ;)))))."
As well as showing off her enhanced skin tone, Katie can be seen revealing her toned legs and bum in some lacy underwear and a pair of blue and gold heels.
We're sure Kieran was more than happy to take this snap!
A while later, 35-year-old Katie also tweeted another picture of herself - this time flashing a lot less flesh.
Posing for a close-up, the reality TV regular can be seen wearing minimal make-up and sporting a very bronzed glow, while wrapped up in a hooded sweatshirt.
She wrote: "Fake tanned myself with crazy angel which I trained to spray tan with."
Aside from evenings of DIY fake tanning and posing for saucy snaps, Katie seems to be truly enjoying married life with Kieran and the couple haven't been shy about admitting how head-over-heels they are for one another.
Last month, Katie declared her love for 25-year-old hubby Kieran by sharing a sweet message on Twitter.
It read: "@kieran0322 you make me so happy, you make me laugh all the time xxx."
The happy couple got married in January 2013 and Katie gave birth to their first child together, Jett Riviera, last September.
