They've insisted their relationship is strictly platonic since leaving the Love Island villa.

But Lucie Donlan, 21, and Joe Garratt, 22, once again sparked up romance rumours as the surfer invited the sandwich maker home to Cornwall to meet her family this week.

The Love Island beauty's sister Emily documented their day on her Instagram stories, where the couple took a dip in the sea and went for dinner at Sam's On The Beach in Polkerris.

Lucie, Joe and Emily and her boyfriend, semi-pro rugby player Noah Sixton, could be seen in the footage jumping off the promenade and into the water.

Lookalike sisters Lucie and Emily both slipped into long-sleeved swimsuits, with Joe and Noah stripping down to their shorts.

Lucie shared a clip of her day, however she failed to show that Joe was also in attendance.

While having a bite to eat later on, Joe and Lucie appeared relaxed in each other's company as they were joined by her parents.

Joe rocked a black T-shirt and covered his eyes with round lens sunglasses as he sipped on wine with Lucie's family.

The pair's meeting did not go unnoticed by fans, who took to Twitter to speculate about the reality TV pair.

The couple's appearance comes after they were spotted emerging from a hotel together the morning after the Love Island wrap party.

Lucie had ruled out the possibility of a relationship with her former partner on an episode of Aftersun last month.

She told presenter Caroline Flack: 'We have stuck as friends. We don't want to put any pressure on anything. It was so much pressure in the villa. Now we are just chilling.'

Lucie's Love Island relationship with Joe was short lived, with him being dumped from the villa after just two weeks on the show.

Lucie then went on to confess to boxer Tommy Fury, 20, that she had begun to develop feelings for him, despite him being in an exclusive relationship with Molly-Mae Hague, 20, who went on to finish as runners up.

Speaking to Ruth Langsford and Eamonn Holmes during an episode of This Morning, Lucie said: 'As we were best friends, we didn't really have that romance.

'When he came out his shell, I really liked him. I spent so much time with him, he was hilarious!

'I needed to get it off my chest and tell him how I felt. I helped Molly-Mae and Tommy get together, so I actually encouraged their relationship.'
