Noth, 54, broke the news to the show Sunday during an interview at the London, Ontario, outpost of Once Upon A Tea Cup, a teahouse of which he and Canadian-born Wilson, 27, are partners.
The couple, who met when Wilson worked at Noth's New York City bar, the Cutting Room, have a son, Orion Christopher Noth, who turns two in January.
In mid-September, Noth denied a U.K. report that he and Wilson were engaged at the time.
A rep for Noth did not immediately return a request seeking comment.
