Romantic Urban also read an open love letter about his feelings for Kidman to the audience, melting the hearts of housewives everywhere watching the show. "He has a way with words," Kidman admitted to Oprah later in the show, "but what always gets to me is when he says he wants to put it into action."

Urban closed out the show with an upbeat performance of his latest single, "Put You in a Song," off of his most recent album "Get Closer," which was released Nov. 16.
