Gabby Allen and her ex Marcel Somerville are set for one very awkward reunion on Love Island All Stars which starts on Sunday. 

The pair met on Love Island back in 2017 and almost a year later Marcel admitted to cheating on her during a romantic holiday to Mexico together leading her to dump him.

The pair reportedly had argued during their time away together so Marcel chose to sneak out and meet up with another hotel guest.

A source said at the time: 'They had a row one night so Gabby went back to their hotel room to sleep. Marcel started chatting to another woman at the bar where they kissed in full view of other guests.

'Marcel and the girl slept together in her room and he left and went back to Gabby's room, but promised to see her the following day when Gabby was at the gym.'

Now they will have to live in a villa together once more as they jet to South Africa for the new series. 

Since Marcel, Gabby has had a series of relationships with the likes of Brandon Myers and Rak-Su singer Myles Stephenson. 

Marcel meanwhile split from his wife Rebecca Vieira last year after it was reported she sent flirty texts to US rapper Slim Jxmmi behind his back. They share young son Roman.

At the time Marcel, 39, who tied the knot with the model in August 2022, 'moved out of their family home' and deleted all traces of her on social media. 

In May 2018 Marcel broke his silence following his sudden split from Gabby and confirmed that he did cheat on her, admitting it's a decision he will 'regret forever'.

Speaking to MailOnline a spokesperson for Marcel explained that the Blazin' Squad star understood his wrongdoings and hoped that one day Gabby would forgive him.

His rep said at the time: 'Sadly the rumours are true, Gabby and Marcel have split up. Marcel can't really defend his actions as he knows he did wrong and will regret it forever.

'Marcel is upset that he broke the heart of someone he loves and someone that he shared so many special moments with, but with all the good times there are difficult times, and sadly Marcel and Gabby had been in a bad place at this stage.

Adding: 'Gabby was a special part of my Marcel's life, and he hopes one day she can find it in herself to forgive him.

'He knows what he did was wrong and is extremely sad about how he has hurt Gabby.'

His comments came a day after Gabby confirmed their 'tough' split and revealed she is 'in shock' from the relationship break-up.

In an Instagram post the blonde beauty thanked her friends, family and fans for their support during the difficult time as she deals with the end of her romance with hunk Marcel.  

She wrote: 'Thank you to everyone for your kind messages, love and support. It's been tough couple of days, I think I might still be in a bit of shock! But I'm sure in time I will be OK. I have the best family and friends around me. I'm a lucky girl.'

Gabby and Marcel met on the 2017 series of summer smash Love Island and quickly forged a romance.   

But their seemingly rock-solid relationship was rocked by claims of infidelity during their Mexican getaway in 2018.

Allegations by The Sun at the time stated that Marcel cheated on Gabby multiple times with different women over the course of a few months.

It was also revealed that the rapper kissed another girl during a night out - but when Gabby's suspicions arose, he managed to convince her that nothing occurred.

The publication claimed that Gabby had her doubts when it came to Marcel remaining faithful in their relationship. 

Back in November 2017, Marcel reportedly locked lips with a woman during a night out with former co-star Jonny Mitchell - and went on to enjoy a meal with her at London eatery STK before partying the night away.

A source said at the time: 'Marcel then invited her to join him at The Box before realising that Gabby has close pals that work there – so he quickly told her not to come.

'At that point the girl was irritated by him backtracking and threatened to tell Gabby what had gone on between them.

'Gabby knew something had gone on that night but Marcel managed to convince her that she had nothing to worry about.'
