The pair have had a tough few months, since leaving the ITV2 dating show, so the hunk revealed he wanted to treat her to something unique to celebrate the holiday.
But, speaking exclusively to OK! Online, he admitted he feels under pressure to make their first milestone special.
When the pair first started dating, after leaving Love Island, Chris made headlines after buying Olivia a stunning Celine bag.
When asked if he felt under pressure to keep up with lavish presents, he explained: “I went away to America to film with Kem, just after Love Island, so I popped into Harrods beforehand to give her a nice surprise and make her happy before going.
“I got it delivered for the morning after I left, her first morning without me.

“I know what you mean [over the expensive gift]! Going forward, it was quite a big gift!
“It was just nice though, it’s been a while since I’ve had a chance to treat someone! It’s a nice handbag! She makes good use of it!”
Chris and Olivia have had a tough few weeks, after a video emerged of the Love Island hunk with his arms around a mystery brunette during a night out in Essex.
However, the pair have sorted through their differences, and are stronger than ever.
And Kem Cetinay’s best friend revealed they were planning to spend their first festive holiday together.
“We’re working out where I’m going to be for Christmas Day and Boxing Day, and Christmas Eve…,” he continued.
“We’ll be together, we’ll be waking up in the same place, but it’s just working out whether it’s going to be at mine or at hers. It won’t be at our own place, it’ll be at one of our family homes.”
Opening up about what he had bought her, he hinted he has a special present in mind.
“I’ve got an idea but I can’t say! I’ve bought her a few things, but I like sentimental things more than actual, big gifts,” he added.
“I’ve got a little plan up my sleeve as well, I just have to keep it all quiet!”
