The blonde reality star shared an image from bed on Tuesday evening (12 July) with a rather cheeky angle as she prepared for her last night in Majorca.
Olivia and boyfriend Alex Bowen finished second on Monday night's finale, which saw Nathan Massey and Cara de la Hoyde crowned winners and split the £50,000 prize, after confirming they were in it for the love, not money.
Although Olivia didn't win, she did come away with a relationship, after she and Alex made it official just before the finale.
"As you may know, trust and security is something I haven't been able to conquer in my past. I came into Love Island with no expectations for that to change and for three weeks it didn't," said Olivia.
"Then my prince walked in. Alex, in short, you have allowed me to learn to trust again. You've been the perfect gentleman and have been so patient with me and my many meltdowns. We've had more tests than I ever thought I could handle, but I've always had faith in us both as a team.
"My feelings for you get clearer and louder every day we spend together and I cannot think of a better way to finish the Love Island journey than to be on your arm. We'll smash this final together and then start smashing a blinder of a future together, stronger than ever."
Alex told Olivia: "I came into Love Island with no expectations. I came here to have a good time and enjoy the opportunity to the fullest. I've realised now that I've done exactly that and it's all down to this one girl. We have this crazy connection and I can't even begin to describe it. When we get out, it's going to be our time.
"I've never felt like this before and I just want you to know, I'm all yours and you're mine."
So romantic, right?
The Love Island cast are now on their way back to the UK, where plenty of them will attend a Coming Home party on Thursday night. We'll also get to catch up on what's been happening when Love Island: Heading Home airs Sunday at 9pm on ITV2.
