The pair have seen off fierce competition from the likes of champion sports stars Steve Davis and Rebecca Adlington, to popular TOWIE star Joey Essex - whose elimination was said to be one of the biggest upsets in TV betting history.
And it seems they're just as shocked as the rest of us, with David saying he felt 'numb' and questioning who is voting for him following Lucy's departure.
Attempting to offer some answers, Kian told the fashion designer: "You’ve come in here and outlasted everyone else and that’s because you are a good guy and people vote for nice people.
"I have a fan base of Westlife fans, but nothing like what Joey has – he has over 2 million followers on Twitter, I have 250k.
"That’s still a lot, but even so he has 1.75m more than me so it’s like, 'what has happened'? It’s way beyond my expectations. I never expected to be here in the final. I’m absolutely gobsmacked."
David added: "I’m deeply honoured, I can’t quite understand this whole thing, and all I know is that I’ve had the most amazing time in here."
Viewers are currently voting for their winner, with the result set to be revealed later in tonight's live show.
