Vicky Pattison has unfollowed fiancé John Noble on Twitter and Instagram after video footage of him grinding up against a mystery blonde in a Dubai nightclub emerged on Sunday night.
The popular reality star is reportedly set to confront businessman John upon his return home on Tuesday.
John, who is now back in the UK, had been enjoying a lads' holiday with a group of pals when he was filmed with the blonde at Billionaire Mansion.
The shock footage shows John looking very cosy with the mystery girl, before she begins grinding in his lap.
An eyewitness told Mail Online that the pair had been “very flirty”.
The source explained: “I was really shocked. I recognised John as soon as he got into the club because I’m a fan of Vicky’s.
“I couldn’t believe that he was talking so close to her. The music was loud so he was leaning into her so that he could hear her. Then she started grinding on his lap.
“It was very flirty and they were really close.”
Meanwhile, a source close to Vicky claimed that she is devastated about the clip, and plans to confront her beau.
“Vicky is upset with the pictures and looks forward to speaking to him when he’s back about it,” a source told Mail Online.
Following the scandal, John posted a fed-up looking selfie online, captioned: “Mood.”
The footage leaked while former Geordie Shore star Vicky was celebrating her upcoming 31st birthday with a group of pals in Brighton.
The pair are set to tie the knot next year, after previously postponing the nuptials due to their busy work schedules and the tragic death of Vicky's best pal Paul Burns.
Meanwhile, Vicky and John jetted out to Dubai last month for a reported “make or break” holiday in the sunshine after a series of blazing rows left their relationship on rocky ground.
A source previously told The Sun: “Vicky and John’s relationship is hanging by the thinnest of threads, but they both think what they’ve got is worth fighting for.
“When they first rekindled their flame two years ago John was exactly the kind of stable man Vicky wanted, but as time’s gone on she’s found it harder to commit to a quiet life up North when all her mates are still down here in London.
“It’s been causing massive rows and John has warned her if she doesn’t start making him a priority over her pals and work it’s over.”
Mirror Online has contacted a rep for Vicky for comment.
