Cheeky Scott shared a photo to Instagram showing Kady lying on the floor of the bathroom next to the toilet, with a pillow covering her modesty.
We're not sure whether Kady knew this photo was being taken or not!
Either way, Scott, 27, told fans: "And that ladies and gentleman is why I love this girl! First night of freedom went so well! Don't worry I'm looking after @kadymcdermott and I will continue to do so for a long time to come.
"Thank you all so much for all your support! It means so much!! It's SO good to be back!"
Plenty of fans took to Instagram to praise Scott and Kady, 20, as being the perfect couple, although some did predict Kady may be none too happy at the photo if she didn't know it was being taken!
One user (@amyjgore85) wrote: "@scottyspecial @kadymcdermott will kill u when she sees this.. absolute lovely couple i voted for use to win think use will have gorgeous babies."
While @kaz1381 said: "She's gunna kill you putting that pic on of her top couple didn't like her at first the way she was with you but she turned it around now think she's amazing such a little sweetie x."
Earlier in the night, Kady had shared a brief Snapchat video showing herself declaring, "Oh my God, I have a boyfriend!" while sitting next to Scott in the back of a car.
They made their romance official in the villa last week, when Scott spelled out the words 'Be My GF?' with towels around the pool, then waited surrounded by candles for Kady to see him. Of course she said yes!
Kady and Scott finished in third place on Monday night's (11 July) final, behind winners Nathan Massey and Cara de la Hoyde and runners up Alex Bowen and Olivia Buckland.
