The handsome TV star, 27, has poked fun at himself by sharing a picture from eight years ago before he found fame on reality TV show The Only Way Is Essex.
In a throwback photo, shared on Saturday (15 August), Mario is at a family meal and looks pretty different to how he does now!
Alongside the snap, Mario joked: "Throwback... I was rocking a mullet."
He added: "A Saturday throwback from 8 years ago... Yes that skinny, goofy sexy little thing on the right is me."
While his super-tan is still present, Mario isn't quite as polished as he is now.
Fans LOVED seeing the old family pic, with one saying: "OMG that's you!!! You have literally transformed into a hunk! Love you."
Another said: "You look so different?!! Xxx."
Now Mario is more famous for looking seriously dapper, and is famed for his toned physique and immaculate grooming.
No wonder he is so popular with the ladies!
The Celebrity Big Brother star has had an eventful few weeks after splitting with his girlfriend Emma McVey and announcing he is leaving TOWIE.
He confirmed the news on Twitter, saying: "I have had a great time on TOWIE and relished the many opportunities the show has given me but after 14 series, I feel it is time to move on and explore something new."
He later added: "I have had a fantastic time on TOWIE and met some amazing people along the way. Some good memories and some bad, but all have helped me become the man I am.
"But I can confirm I have decided to leave the show and pursue some new adventures! Thank you for all your comments today. It means a lot #TOWIE #emotional."
A spokesperson for the ITVBe show said the door is open for Mario to return.
