A source told the publication: ‘They had a row one night so Gabby went back to their hotel room to sleep while 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.’

In messages published by The Sun, claiming to be between Marcel and another woman, he wrote: ‘Tomorrow I’ll be available. We can have some day sex.’
However their second rendezvous was said to be plighted when Gabby returned back to her hotel room early, with Marcel texting: ‘I’m going to the gym but I’ll try and catch you on the way. Actually the plan has been ruined. She’s back.’
In other messages, he allegedly went into the crux of the couple’s relationship problems, saying: ‘There was a lot of jealousy on her part which caused a lot of arguments.
He continued: ‘I know what we did was wrong but at the time I felt she was pushing me away and that’s why it all went down.’
MailOnline has contacted Gabby and Marcel’s representatives for comment.
The pair were pictured together as recently as last week, where they arrived hand-in-hand to a Boohoo launch party in London.
Gabby recently opened up about the racial abuse she has been subjected to due to her relationship with the former Blazin’ Squad member.

In an exclusive interview with MailOnline last month, the reality star revealed she had been branded ‘dirty’ among other cruel slurs in their relationship.
The Liverpudlian beauty shared: ‘When I first came out, I was so overwhelmed because I didn’t think people in this day and age still thought like that people said I was naive but I’ve always been in a multicultural society so I haven’t ever been in that position before.’
‘If you take time out to try and hurt me and to try and put that out there then there’s something wrong with you. If it’s that bad I can’t ignore it. The worst thing (that’s been said) is that you’re the genocide of your own race…’
‘I can’t believe people think like that. Like, where do you live? What do you think when you see ethnic people, do you know what I mean? Marcel is so laid back he just hates that i have to deal with it. I get it more than he does.’
