The reality TV star reckons producers banned from saying long words because he wouldn’t be understood.
“I had to dwindle it down a bit when I did ‘TOWIE’,” he told The Mirror.
Mario also claimed that he is actually much more articulate in his day-to-day life than he appeared on screen.
“I was a bespoke tailor before so I can’t speak to wealthy clients like ‘Aw right me geezer’ – it sounds horrible. When I was on ‘This Morning’ for a segment ,Holly Willoughby said: ‘Mario I mean this in the nicest way possible, you’re really intelligent, I had no idea!’
He added that he was pleased he didn’t have to pretend to be less intelligent, saying: “I don’t do it anymore, I bought my soul back from the devil.”
Mario quit the ITVBe reality show last year, following a suspension for breaking the show’s rules for promoting slimming on social media.
He said at the time: "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."
She wrote in her new! Magazine column: “He’s an amazing - such a great guy and a brilliant help. I couldn’t have done this move without him."
