Nicole Kidman is opening up about her happy marriage to Keith Urban. Although the cute couple married when she was 39 and he was 38, the Oscar winner says she's glad to have found true love. Kidman said, "Keith always says, ‘We're lucky we met late in life. The sadness of that is we can't have six kids together, but the greatness of that is [we are done] with all the other stuff, so now we are totally present for this.' That's a great thing to hear from a man." The lovebirds recently celebrated their eighth wedding anniversary during one of Urban's concerts and he gave his wife a loving shout-out from the stage. "Eight years, baby girl," Urban said. "This song is for you. I love you so much."
