Mario's picture was favourited on Instagram more than 11,000 times, with fans leaving a slew of very complimentary comments. One simply said: "There are no words…"
The photo came after Mario issued a public apology to TOWIE's cast and crew, friends and family and the show's fans for his behaviour in the past.
He was noticeably absent throughout the recently finished twelfth series.
Essex favourite Mario recently told The Sun on Sunday: "After a few personal issues I went off the rails."
He admitted to "excessive partying over a three-month period" which had a negative effect on his health and wellbeing but now, he's taking care of himself and feeling better.
"I have been seeking professional assistance and am now fit and well," he added. "I hope that the producers and ITV will see my genuine remorse and consider allowing me to return to the show."
It's rumoured that the thirteenth series of TOWIE will kick off with a special episode in Ibiza, which begins filming in September.
A source told Reveal: "Ibiza is a favourite holiday spot for the cast of TOWIE and they often party there as well as Marbella, so it's only right that they should end the summer filming there after they kicked off the season in Marbella."
