You learn something new every day. Certainly Cody Alan of "CMT" did, as he was interviewing Keith Urban. Keith explained that he was backstage at a Luke Combs concert chatting with his fellow country superstar and was introduced to Luke's wife. "He said, oh this is my wife Nicole, and every time I meet someone called Nicole, I jokingly go, 'oh, we just met and I've already got you tattooed on my arm.' And she goes, 'Well, actually I was named after her (Keith's wife, actress Nicole Kidman)." Kidman is 57; Luke's wife is 30. We did the math; by the time Luke's wife was born, Kidman was already a big star, having played in huge Hollywood movies like "Far and Away," "Days Of Thunder" and "Batman Forever."
