Season and place: Season four, winner
Underwood is so successful that it's easy to forget she started on American Idol. The country star has won seven Grammy Awards, 16 Billboard Music Awards, 11 Academy of Country Music Awards, and eight American Music Awards. Her debut album, Some Hearts, broke several records, becoming the fastest-selling country album of all time. Billboard even named it the No. 1 country album of the 2000s, and Time has named Underwood one of the most influential people in the world. Her net worth is reportedly between $55 million and $70 million. She's so popular that she even released a Greatest Hits: Decade #1 album last year. Need we remind you of her role in NBC's live version of The Sound of Music? This girl has it all.
