The pretend gesture happened while Katie was filming scenes for her reality show My Crazy Life with her boyfriend as they holidayed with her mum Amy.
Kris is seen acting nervous and tripping over his feet as he attempts to put on the perfect romantic display for Katie.
The personal trainer, 30, is seen leading the mum-of-five, 40, to a table strewn with rose petals in an empty restaurant.
In an interview filmed later, he tells her: “I wanted the trip to be romantic but I was so nervous that I would blow it.”
Back at the restaurant, a waiter delivers a bottle of wine with a sparkler attached to it.
Kris then tells Katie he’s got her “a little present” and passes her a small black ring box.
She opens it and looks over to him and the scene cuts off, with a voiceover telling fans they’ll have to tune in to find out what happened.
But could we already know?
Last week, Katie dropped a massive hint she and Kris were engaged as she took to Instagram to share a snap of herself wearing a huge diamond ring.
She wrote: “Take me back to Thailand @krisboyson,” alongside a diamond emoji.
Fans immediately started questioning if Kris had popped the question.
One asked: “Is that an engagement ring?”
While another told her: “So glad you finally found someone decent. You are glowing Katie”
However, Katie’s representatives told Mirror Online the star is NOT engaged.
And Katie later told the Daily Star : “I do it on purpose. You know what I’m like!
“I’ve just got to stir the pot haven’t I? I love it.”
It was once reported that Katie had told Kris he had to propose in front of the cameras for her reality TV show, or she’d say no.
Katie was apparently keen to make the personal trainer husband number four, but only if he pops the question on her reality show, My Crazy Life.
A source told The Sun : “Kris and Katie talk about marriage all the time and it’s pretty much a given they’ll get engaged very soon.
“But Katie’s made it clear to him that if he’s going down on one knee, it’s got to be in front of the cameras.
“She wants a big romantic gesture, something really over the top, but she’s agreed to put her whole life on the reality show so it needs to be filmed.”
The insider claimed that Katie had basically told Kris she’ll only say yes if the whole thing goes down in front of the cameras.
* My Crazy Life airs Mondays at 10pm on Quest Red.
