Fans were set to see Dean navigate a chat with this year's Married At First Sight contestants: Melissa Lucarelli, Mick Gould, Cyrell Paule and Ning Surasiang at Enmore Theatre on May 19.
One person who won't be going is ex MAFS contestant Nasser Sultan.
The former groom sent Dean a series of rude messages expressing his disinterest in the show.
