It's been six years since Mark burst onto our screens alongside Lauren Goodger, Amy Childs and James 'Arg' Argent, and since then, whether you love it or hate it, The Only Way Is Essex has arguably become a cultural phenomenon.
Mark has told The Mirror that plans are now underway to celebrate the success and impact of the popular ITVBe show, and he'll be returning to voice the "serious" programme.
He explained: "We are doing an anniversary episode and talking about the success and power of the show. People like to talk about TOWIE in a bad way and tarnish it. But Brentwood high street has changed so much, and the local hotels do great business because of it."
Mark will be examining the impact of TOWIE on those local businesses, and how the success of the show has led to special The Only Way Is Essex tours showing off filming locations.
The 29-year-old was one of the original TOWIE stars, dominating the first three series' storylines with his on-off relationship with then-girlfriend Lauren Goodger. He left in 2011 to pursue other opportunities and now has a thriving presenting career, taking the reigns on Take Me Out: The Gossip, his own Heart FM show, and hosting CBBC programme Dengineers.
Although he's long left the show, he's remained loyal to it, returning to present All Back To Essex live shows.
