Jack Fincham joked he and girlfriend Dani Dyer will “do bits” as soon as they leave the Love Island villa.
The couple have remained celibate for the entire eight weeks of the ITV reality show, despite being in a committed relationship.
When the twosome were quizzed about their romance by Caroline Flack, the cheeky host asked when the love birds would “do bits”.
Following cheers from the crowd, Caroline probed: “Tonight?”
Responding without hesitation, Jack quipped: “Yeah definitely, I can’t wait.”
He and Dani, 22, were then crowned the winners of Love Island 2018, beating Laura Anderson and Paul Knopps.
After the pair were tasked with choosing between two envelopes, with one containing nothing and the other containing £50,000.
The person who held the envelope with £50,000 had to decide whether to take it all or split with their other half.
Jack, who had the money, was then asked what he wanted to do with it, to which he replied: “I’m sharing it, obviously.”
When Dani was asked if she ever doubted whether Jack would share the prize money, she insisted: “No never.”
Earlier in the show, viewers watched the lovers read out heartfelt letters to one another, with Dani admitting she never believed she’d find someone like Jack in the villa.
Through teary eyes, she said: “Jack, when I first entered the villa eight weeks ago, I never imagined that in a million years I would have met someone as special as you.
“From our first date together on the beach, to our trip in a hot air balloon, we have already made so many special memories, and I can’t wait for even more.
“I have had the summer of my life in here and I owe so much of that to you, Jack.”
Holding back the tears, Jack gushed over Dani and insisted she changed him for the better.
“You are everything that I’ve ever wanted in a girl,” he offered.
The fourth series concluded with runners-up Laura and Paul, whilst Josh Denzel and Kaz Crossley placed third.
Host Caroline Flack announced fourth place was given to Megan Barton Hanson and Wes Nelson.
After two months of the reality TV show, applications for the fifth series of Love Island are now open.
Love Island series 5 returns next year.
