Keith Urban

After overcoming a serious drug addiction, Australian country singer Keith Urban began paving his way to superstardom in 2001. The country cutie took America by storm with chart-topping singles like "Somebody Like You" and "Days Go By," winning him Male Vocalist of the Year at the Country Music Awards in 2004. The following year, Keith hit it off with fellow famous Australian Nicole Kidman and the two tied the knot in 2006. With Nicole by his side, the singer checked himself into rehab just months after. He bounced back by 2007 and released his greatest hits album, all before Nicole gave birth to their first child, Sunday Rose. With everything back on track, Keith released his first No.1 album, Defying Gravity, earning him two Grammy's in 2009 and 2010. Later that year, the Aussie couple welcomed their second daughter, Faith Margaret.
