The former TOWIE star, who presents spinoff show Take Me Out: The Gossip, told ITV's Loose Women that one benefit of being famous is everyone knows he's married to Michelle Keegan.
He said: "Do you know what? I am being genuinely serious. None of the girls have ever gone there."
When pressed about the crew: "No, not the crew either!"
Cabin crew? "No!"
Mark said: "There are positives and negatives of being in the public eye. One of the positives is nearly every girl who sees me knows I have a wife and don't go there. I go to a club and they know I am taken."
The 29-year-old said his main career focus going forward is presenting and hosting. As well as Take Me Out: The Gossip, he hosts CBBC show The Dengineers and his own show on Heart FM.
He said he'd probably never do another reality show after I'm A Celebrity... Get Me Out Of Here and Strictly Come Dancing. "I did the jungle which I always watched and always loved and wanted to do it after TOWIE to show the real me. Never say never but I've done Strictly and the jungle and that's it for now. I want to focus on my hosting and presenting."
