Turns out, Sophie and Nathan enjoyed a smooch many years ago, before they became co-stars on the MTV reality show. Sophie made the confession while chatting exclusively to Reveal ahead of Geordie Shore's new series, and said about Nathan: "We've touched tongues."
Sophie told us: "Nathan told me that I'd kissed him, I'd necked on with him years ago in a club."
Well there's something we *didn't* know about the pair.
Of course, now, both Sophie and Nathan are happily loved-up. Sophie has been dating boyfriend Joel Corry for several years now, while Nathan is oh-so-smitten with his boyfriend too.
Joel had made several appearances on Geordie Shore back when Sophie was first a regular cast member on the show (she was axed after seven series for alleged "offensive behaviour"), and while he could potentially return for more now she has replaced Charlotte Crosby on Geordie Shore, Nathan has ruled out an appearance from his beau.
Fans are often treated to a slew of selfies of Nathan and his boyfriend on Instagram, but Nathan told us he isn't planning on bringing him on camera - he likes to keep their relationship separate.
Nathan said: "I'm with a boyfriend now. He won't be coming on the show, it's difficult because he's got a serious job. I like the fact that we've got a separate life, and when we stop filming I can go back to that."
Geordie Shore fans will get to see the cast head overseas this series and travel around different party resorts in Europe, including Magaluf, Kavos and Ayia Napa.
It will be the first series without Charlotte, after she decided to quit Geordie Shore at the start of June. But, the blow of her absence has been slightly softened by the re-addition of Sophie to the cast.
Speaking about her return to the house, Sophie said: "I was on Birthday Battle... it was so good and everybody was back, so I was in my comfort zone, but with this I wasn't so much. Everybody else had done series recently and had this little clique and stuff. Going into it, I had a boyfriend and everyone had relationships and stuff going on in the house so it felt very different. It was hard to go back in, but after a few weeks it was like it always was."
There are definitely no hard feelings between the girls, though, as Sophie and Charlotte are often seen together on social media. In fact, they are currently on holiday together!
