The reality TV star, 36, posed for photos in a cute summer dress - which showed off her new and improved natural boobs...
And, as one fan commented, Katie "looks lovely [but] so weird without her big boobies". Yep, we have to agree it takes some getting used to!
The navy blue and white striped frock with red contrasting detail is a far cry from the outfits we used to see Katie in when she was a whopping 34FF!
Now five cup sizes smaller after a boob reduction, Katie - aka Jordan - is a much more manageable 32B.
After posting the snap, Katie's fans were quick to comment with one saying: "It seems strange seeing you without a massive cleavage, looks a lot better. #cute."
Another thought Katie looked "fabulous" and one said she was rocking a "school teacher look". Must be those black-rimmed spectacles!
Other fans added: "You look so much better!
"Looking amazing with the new boobs. Takes years off you!"
Katie was filming a video shoot with her Celebrity Big Brother 2015 pal Kavana, who she bonded with in the house before going on to win the series.
While she didn't explain exactly WHAT she was doing in the video, she enjoyed teasing her fans with pictures from the day.
She said: "Loved doing video shoot today with @kavana_official can't wait to bring my record out and video now #watchthisspace."
What record, Katie?! Now we're intrigued...
Alongside pictures of her posing with make-up artist Mikey Kardashian and husband Kieran Hayler, she also wrote: "Enjoying video shoot with @kavana_official @MKardashian @makeupbysallyc #dejavu."
Before arriving on set, Katie tweeted: "Can't wait to see you @kavana_official it's going to be a fun day are we allowed to say what we are doing."
Sadly, neither let slip what Katie's involvement was - although we DO know Big Reunion star Kavana was recording the video to his new single Deja Vu.
The single is believed to be a collaboration with fellow CBB housemate Alexander O'Neal.
