The country singer - who married the `Moulin Rouge` actress in 2006 and became a father to Sunday Rose in July 2008 - thinks their first child is fortunate to have inherited her mother`s enviable long pins rather than his. He said: "I think she`s a combination of both of us so far. But she got my wife`s legs, which is very lucky for her. She sure didn`t deserve mine." The 42-year-old star says he is constantly amazed by Sunday Rose and loves being a father to her. Speaking about fatherhood, he told People magazine: "It`s always something new, that`s what I love about it. And maybe other dads are different, but for me, it keeps coming on. "I`m like, `Oh my God, that`s my daughter.` It`s beautiful. Absolutely beautiful. I feel very grateful for it." Keith also hinted the couple may add to the family in the near future but aren`t expecting just yet. When asked if they would be trying for another baby, Keith replied: "I`m not, NOT trying. So we`ll see." Nicole has two adopted children - Isabella, 17, and 15-year-old Connor - with ex-husband Tom Cruise.
