Los Angeles, Actress Nicole Kidman's husband Keith Urban thinks his wife is a "very good" gambler, but she says she is very cautious. "She's very good. She's disciplined," he said. However, the 48-year-old actress says she is always cautious with her money and only bets "a little amount". "Well I'm not very good. I have a little amount of money, I go and bet that and then I'm done. I'm that kind of gambler, I'm not going to bet the house," Kidman told etonline.com. The actress adores her husband's "passion" when it comes to his work. She spoke about the 48-year-old star's upcoming LP, and said: "It is such a crazy good album. "I've been living with all the songs -- and even the songs that didn't make the album. I've seen the work he puts into it and the love. He's a musician, so every little tiny detail is all him, and I love that. I love that he's passionate about his music."
