Mario announced he was quitting the show after four years on Monday (10 August), and he received an outpouring of messages from fans and co-stars, many of which said how much they'll miss the 'Italian stallion'.
Joining the show in 2011, Mario has been involved in some of the show's biggest storylines, something which he admits has been "good and bad" in equal measure.
In a message to fans via Instagram, Mario said: "I have had a fantastic time on TOWIE and met some amazing people along the way! Some good memories and some bad, but have all 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."
Mario also shared a photo collage highlighting his time on the show. Remember his bromance with longtime friend Chris Drake, aka Little Chris? And when his ex Lucy Mecklenburgh threw *that* drink all over him?
And what about when Mario and Ricky Rayment got their feet tattooed? And when Mario's secret romance with Chloe Sims was revealed?
Mario joins a growing list of stars who have left the reality show this year. While Dan Osborne was sacked, Charlie Sims, Jasmin Walia, Ricky Rayment and Elliott Wright have all left the show.
