Despite coupling up much later on in the show, Katie and Adam are clearly fond of each other and that showed as they both took to Twitter following last night's final.
The pair shared the same photo of themselves together in the villa, before adding their own sentiment alongside it.
Adam gushed: "No girl has made me laugh as much as @katiesalmon24 and she's #LoveIsland."
That was (obviously) not before he had treated us to one of his much-loved metaphors, tweeting: "The phone notifications coming at me today is like when water from a tap hits a spoon when you're doing the dishes & sprays all over you."
Katie, meanwhile, told fans: "Crazy journey! Wouldn't have it any other way so much fun. We are so happy with the support #kadam @AdamMaxted."
Fans will be eager to see what happens with the pair now they are on the outside, as their relationship had been hotting up towards the end of this series.
Initially, Katie had chosen to couple with Sophie Gradon, but was left hurt and confused when Sophie told her she couldn't continue in a couple with her and quit the villa to sort things out with boyfriend Tom Powell.
She had shown an interest in Adam before coupling up and with Sophie gone, that left Adam to make his move.
He and Katie then coupled up and shared their first kiss on their first date together. Despite locking lips on several occasions, though, Adam was wary to take things further with Katie in the hideaway and turned down the chance to have sex with her - as he didn't want to jeopardise his WWE dream.
She, meanwhile, didn't rule out a future for them on the outside now the show has finished and has said she would be keen to visit Adam in Ireland.
Speaking about her beau on the show, Katie said: "We're getting on nice. I like the fact that he's such a chilled laid back guy. I'd go to Ireland and see him, definitely. I'm looking forward to getting to know him more because it still is early days, obviously. It's nice you can have someone in here you can have a little kiss with and a little cuddle."
We'll be keeping our eyes peeled for any updates on the romance front, then!
