Mario had been suspended from the ITVBe reality show in May after promoting slimming pills on social media, meaning he was not allowed to join his co-stars in Marbella.
However, as filming resumes with cast in Essex, Mario has now joined his co-stars.
He told The Sun: "I was a bit gutted not to go to Marbs this year but, on reflection, having seen all the dramas they had out there it was probably a blessing in disguise.
"I am pleased to be back filming in Essex and looking forward to having some fun with the lads."
It was hoped that Mario would make an imminent return after Lime Pictures' Derek McLean commented earlier this month: "We have to be very strict about that. We hope Mario will be back but, if he isn't, we will be perfectly fine with that."
