You don't have to be a country music fan to adore Carrie Underwood. In 2005, the Oklahoma native was thrust into the national spotlight when she won American Idol, and the sweet Southerner quickly evolved into one of country's biggest stars. She's been at the top of her game — and at the top of the charts — ever since, charming even those who don't keep country songs on their iPods. Beyond all the music-related praise, though, Carrie's also inspired fans with her offstage personality and her real-life romance with Mike Fisher. The couple recently welcoming their first child together, Isaiah Michael, and this week, Carrie turns 33. To celebrate her birthday, take a look at the country star's evolution from American Idol to now!
