The pair got close close under the sheets a total of 30 times, according to someone who's job it is to actually count these things.
That compares to the 23 times that winners Cara De La Hoyde and Nathan Massey enjoyed adult time despite them being together from Day 1 while Olivia and Alex only first hooked up on Day 19.
Cara and Nathan won the £50,000 prize fund in last night's Love Island final, deciding to share the prize fund equally in one last twist.
Olivia and Alex finished as runners up in the final, beating Scott and Kady into third place while Katie and Adam rounded off the results in 4th.
This year's series of Love Island had proved a mega hit in the ratings with viewing figures double that of last year.
As a result ITV have already announced the show will be back for a third summer next year.
Host Caroline Flack said before the final yesterday: "It's made you laugh, it's made you cry - people have really invested in it this year.
"You do get hooked on people's relationships, the cast has been fantastic, and the pace has been brilliant. It's been escapism this summer - with all the things going on."
