She and Alex have been dating for around five months now and proving she is still just as smitten with her co-star boyfriend, Olivia couldn't resist showing off Alex on Instagram, pecks and all.
Yep, she chose to post a snap of Alex topless and said: "My baby too much."
Olivia added a love heart emoji alongside her post and within an hour of sharing it on Instagram, it has already received over 13,000 likes.
It's safe to say many fans appreciated a glimpse at Alex's buffed up bod, with one user commenting: "He's gorgeous you're very lucky."
Another added: "Your boyfriend is so dreamy, can I meet him?" While another said: "Love the love between you two, couple goals."
Some of Olivia's followers picked up on the fact Alex is wearing a ring on his finger, and while they questioned whether it was a wedding band, others were quick to point out it's actually on his right hand and the mirror is playing tricks on us all.
Of course, that would also mean that Alex and Olivia would have to get engaged first. They aren't currently, but Alex has revealed a proposal could be on the cards soon.
He exclusively told Reveal in September: "I've never been this happy. Before I went on Love Island, I didn't even have an idea of when I'd move out of home - now I've got a girlfriend, we're getting a house together and I'm happy. I'm not going to say it's going to be a year until I propose because then she'll be there like, 'Erm, it's a year to the day and you haven't proposed!' So it could be less, it could be more. She's already sent me a picture of the ring that she wants though."
Olivia's post comes after she and Alex recently moved into their very first home together. Alex had been living with Olivia at her Essex flat, but now the couple have bought their first house and are currently settling in.
Soon they'll be welcoming a new arrival, and it sounds like Alex won't be the only one Olivia will be sharing smitten photos of.
She recently confirmed that the pair will be getting a dog. Olivia tweeted a photo of a litter of puppies and told her followers: "So our little boy has been born 22/10/16 @ab_bowen07."

Olivia had previously spoken to us about her and Alex's plans to get a puppy, but said, at the time, they were waiting until they had secured their house.
She said: "We're getting a bigger house - three bedrooms - so it's getting very serious. We're going to be saying in Essex and will have a garden for the new arrival.
"We've found someone that has a French bulldog litter due at the end of October and I can't wait for him to be born."
