Elliott was rumoured to be having a cameo in the reality series, and that was all confirmed when he appeared in the teaser for next week's episode.
In a preview clip, Elliott speaks to Suzy White where he dishes out advice: "You've got no building license, you've got no windows in and you're trying to say you're going to open in two days? Oh Su, what are you like?!"
This marks Elliott's return to TV for the first time since he quit TOWIE in June this year. Elliott, who is the cousin of Mark and Jessica Wright, announced his exit after two years on the show this summer.
He moved to Marbella following the end of series 14 after announcing to his now ex-girlfriend Chloe Sims that he was leaving Essex to launch his new restaurant, Olivia's La Cala.
Elliott returned for the 15th series of TOWIE as the cast went to Marbs to film two special episodes, but he announced his departure soon after.
Elliott isn't the only familiar face to pop up on Life On Marbs, as TOWIE star Ferne McCann popped up on our screens last month where she gave close friend Jordan Sargeant advice on her love life.
