Love Island All Stars was in part so successful the first year because it brought together so many people with shared history, and those reunions make great TV.

Think, Casey O'Gorman and Georgia Harrison, and of course Callum Jones and Molly Smith. And for the second ever All Stars series things are no different.

From literal exes Gabby Allen and Marcel Somerville to Harriett Blackmore and Ronnie Vint, this series has created some unlikely reunions. However, while most of the islanders who have history have been revealed out in the open - looking at Casey, who whispered "I slept with her" when Tina Stinnes walked in - fans of the show discovered a connection that wasn't mentioned, until now...

Nothing gets past Love Island fans and this time they uncovered history between Luca Bish and Harriett before it was even mentioned on the show.

What is Harriett Blackmore and Luca Bish's shared history?

The Love Island sleuths have been at it again! It was known before her first time on the show that Harriett was friends with YouTuber and internet personality Saffron Barker but it turns out their friendship group included Luca.

One fan found old videos from Saffron's YouTube channel which show Luca and Harriett together. They shared them to TikTok with the caption: "why have we never seen harriet and luca interact even though they've been friends since they were little? [sic]"

The caption reads: "like they were in the same friendship group and everything."

In the clips, Luca and Harriett are seen at Saffron's 18th birthday party and one clip shows Harriett in the car with Saffron and Luca appears in the backseat window.

People in the comments dropped even more lore, adding that the Brighton locals went to school together.

One fan said: "This is how you know we only see about half an hour cause HUH".

But other more observant viewers have pointed out how they've noticed Harriett spending time around Luca and Grace Jackson, with one saying they are giving off "sibling vibes".

Explaining why we might not have seen much Luca and Harriett content, one fan said: "they don't really prioritise friendship related stuff. but when harriett isn't talking to grace alone she's almost always sitting with luca so they definitely do [sic]"

If you've been watching Love Island All Stars 2025, you will have noticed how friendly Grace and Harriett are which is due to them both being on series 11 last summer.

What happened between Love Island's Luca and Harriett?

After an intense game, which caused a row between Harriett and Casey, Luca and Harriett addressed their friendship for the first time on All Stars.

Harriett was upset that Luca was hanging around with Casey even though he was telling everyone about their argument and complaining about her - in Harriett's words he was creating a 'hoohah' about it.

She expressed to Ronnie and Grace that he didn't think Luca had her back in the villa like how she would have his. And Ronnie acknowledged how her feelings about Luca were "deep" because they grew up together.

When she spoke to Luca about it he explained that in the outside world he would have her back 100% but he couldn't back her in the villa if she was in the wrong because they were all a "family" in there.

"I wouldn't need to defend you if you didn't get yourself in those situations," he told her.

Upset by how the chat went, Harriett went to the glam room where she told Ronnie: "I just know that the friendship's done... he just doesn't care, he does not care about my feelings at all.

"I'm done with him, I don't want to be friends with him anymore."
