Carrie Underwood has been named the top-earning American Idol alumni.

The country music star and 2005 winner topped Forbes magazine's annual list thanks to her staggering $31 million income over the last year, with a sell-out tour, albums and beauty deals under her belt.

Kelly Clarkson, the first ever Idol winner, came in second place with $7 million with the earnings of two albums and concerts, each scoring her quarter of a million dollars. The third spot on the list is a surprise tie between season 8 winner Adam Lambert, who landed a guest role on Glee, and 2012 winner Phillip Phillips, with $5 million each. The lesser-known Phillips' winner's single "Home" fared better than any in the show's history, shifting over 4 million copies.

Chris Daughtry was third with $4 million thanks to performing over 80 shows with his eponymous rock band. Baby-faced country singer Scott McCreery ranked sixth with earnings of $3 million, while season 5 winner Taylor Hicks - who is the only Idol alumni with a Las Vegas-residency - came seventh. Broadway star Fantasia Barrino, Dancing with the Stars contestant Kellie Pickler, Smash singer-and-actress Katharine McPhee and Dreamgirls star Jennifer Hudson rounded out the top 10.
