The This Morning presenters were talking to the money-saving expert about ways to save money as a couple, including the possibility of sharing debt.
However, things quickly became very awkward when Eamonn made a remark about Ruth's spending habits and insisted he wouldn't help his wife out if she was in debt.
He asked: "What if you don't want your partners debt moved to your account?
And, Ruth wasn't impressed by his comment as she hit back: "That's very chauvinist, I always pay my debt. Take that back right now."
