Take Me Out host McGuinness, who married model Christine Martin in June of this year, told The Mirror that his wife is "great company" and that he frequently hurries home from London to spend more time with her.
McGuinness said: "I know it sounds cheesy but I don't want to be apart from her - I still live in Bolton and try to drive back straight after working in London so I can be at home. She's everything to me.
"I could never have married a trophy wife. It would drive me potty not to be able to have a conversation with my partner - or a laugh. Yes, she's gorgeous but she's also really good company and the least showy-offy girl you'll ever meet."
McGuinness also quipped that the only "talent" he would be able to show off in the final round of Take Me Out is making mashed potato, adding that succeeding in the quick-fire dating show is "all about confidence".
The comedian previously revealed that he would love to become a father and is a "romantic" at heart.
Take Me Out returns on January 7, 2012 on ITV1.
