The reality star turned 30 over the weekend and was sharing birthday messages from his pals on his Instagram when one tribute in particular caught the attention of eagle-eyed fans.
Tyne-Lexy Clarson - who starred in the 2017 series of the ITV2 dating show - posted a snap of her and Jack looking VERY cosy as she cradled his face in honour of his big day and got tongues wagging in the process.
Alongside the photo, Tyne-Lexy wrote, “Happy birthday babe! @jack_charlesf have the best day 🎂🎈❤️.”
This isn’t the first time the two Islanders have been linked as they were rumoured to have grown close while filming British gangster flick The Last Heist together back in February.
Jack and Tyne-Lexi play a couple in the film, so could this be life imitating art?

Yewande Biala and George Rains were not even in the villa at the same time but outside they seem to be having a whale of a time. Fans were buzzing in August when the Casa Amor star appeared to have Yewande's makeup all over his face.
The pair filmed their scene under strict Covid conditions in a club in London and reportedly hit it off on set, with an onlooker telling OK!, “Tyne and Jack got on really well and were having a lot of fun playing their roles.
“There was a really great chemistry between them.
“You could tell that Tyne was a trained actress she worked really well in front of camera and was a total natural.”

Tyne-Lexy is the third Love Island star Jack has been linked to after he reportedly enjoyed a secret romance with co-star Laura Anderson last year following his split from Connie O’Hara.
“They have always been close, but lately they’ve grown more romantic with each other,” a source said of Jack and Laura, who both starred on the 2018 series of the ITV2 show.
“Laura is based up in Scotland but sees Jack when she’s in London. They really like each other and have even locked lips,” they added to The Sun.
Jack even added fuel to the fire when he shared a throwback snap of the pair together, but tagged the UK photo in Dubai, seemingly implying that he and Laura were together there...
