As a tot, the Kiwi cowboy Keith Urban moved to the Australian farming town of Caboolture where he spent his childhood milking cows, playing ukulele, developing a diehard love of Glen Campbell and eventually dropping out of school at 15 to pursue music. After scoring four No. 1 singles down under in 1991, he moved to Nashville to see if he could make it in country's capital. While a struggling musician, he developed a cocaine addiction, for which he eventually sought treatment in 1998. His first U.S. solo album, released a year later, featured the eventual 2001 No. 1 hit "But For The Grace Of God." After posing for Playgirl in 2001, he and his highlights released sophomore hit Golden Road. Pronouns prove lucky as "Somebody Like You," "Who Wouldn't Wanna Be Me?" and "You'll Think of Me" all become No. 1 singles. His first Male Vocalist of the Year win at the Country Music Awards comes in 2004 on the heels of his first headlining tour and third record Be Here. In 2005, he moved up to Entertainer of The Year and met future wife Nicole Kidman at a dinner for famous Aussies. She was by his side when he picked up his first Grammy in 2006, the same year that the couple wed, and when he returned to rehab just four months after the ceremony and a month before his aptly titled Love, Pain & the Whole Crazy Thing is released. Again clean, the tattooed (love, a thunderbird, an eagle and love conquers all in Latin) twanger tried out fatherhood on two daughters, Sunday Rose (2008) and Faith Margaret (2010 via surrogate), and judging on American Idol.
