On Lorraine, Amber explained, "I saw her in a bar and she said to me, 'Can you put me forward?' I said, 'Yeah, that's fine, I'll do it.'

Lucie Donlan and Arabella Chi
During Love Island 2019 it came to light that Lucie Donlan and Arabella Chi kind of knew each other before going into the villabecause they were talking to the same guy... Love Island 2018 star Charlie Frederick. However their awkward past didn't stop them from being friends in the villa.
Molly-Mae Hague and Kendall Rae Knight
It's well known that Molly-Mae Hague was an influencer before her time on Love Island and it turns out she went on a press trip with Kendall Rae Knight just a few months before going into the villa.
Maura Higgins and Curtis Pritchard
They were the 2019 couple no one saw coming but after Maura Higgins and Curtis Pritchard went official with their romance, there wereclaims that they'd known each other for YEARS. It all came about after a Dancing With The Stars pro claimed they'd 'cast eyes' at each other backstage years before, back when Curtis was on the show as a professional dancer and Maura visited the set a few times. Hmm.
We've seen a lot ofLove Island stars recouple outside of the villa but have you ever thought about the Islanders who dated before going on the show?
During the 2016 series, the Islanders were floored when Tom Powell's ex-girlfriend Emma-Jane Woodhams entered the villa.
When Chloe Crowhurst went on the show a year later, TOWIE's Jon Clark hit out at her and claimed they were in a relationship and was shocked to see her on the Love Island line-up. However she went on to deny his claims.
Then in 2019 a similar set of events happened when Charlie Frederick claimed that he was dating Arabella Chi when she went into the villa and thought they were in a relationship.
Arabella hit back at his claims and admitted that although they were seeing each other "about a month" before she went into the villa she added, "He knew it wasn't going to be like a full relationship".
And in Love Island 2022, Gemma Owen's ex Jacques O'Neill stepped into the villa as a bombshell.
