Kelly Clarkson's 'Stronger' Outsells 'American Idol' Rival Carrie Underwood (PHOTOS)
Thirty-year-old Clarkson just moved 3,510,000 singles of her latest smash "Stronger (What Doesn't Kill You)," which went to number one on 11 different Billboard charges, including the Hot 100, Hot Digital Songs, Adult Top 40 and Hot Dance Club Play. It even spent five weeks at the Adult Contemporary chart's summit.
What was the song that previously held the record for best-selling single by an American Idol singer?
"Before He Cheats" by country superstar Underwood, 29. That single moved 3,509,000 copies since it hit the charts in 2006. It wasn't exactly a chart-topper: the song peaked at number 8 on the Hot 100 but stayed on the chart for a whopping 64 weeks.
Clarkson's "Stronger" shows no signs of weakening: in its 27th week on the chart, it rebounds from number 22 to 21. Her latest single, "Dark Side," recently premiered.
Underwood does have some consolation: she's still the best-selling albums artist from American Idol. She's sold 13,205,000 albums; Clarkson has moved 11,664,000.
And Underwood is adding to that total: according to Nielsen Soundscan, her new Blown Away album sold 15,000 copies last week, bringing its total to 600,000. Clarkson's Stronger album moved another 7,000 copies, bringing her to a total of 864,000.
Another past Idol didn't do quite as well: Casey Abrams -- who finished in sixth place on the show's 10th season -- sold just over 4,000 copies of his self-titlted debut. Adam Lambert's "Tresspassing," meanwhile, dropped to number 115 (and a sales total thusfar of 135,000).
They aren't the only AI singers on the album chart: Scott McCreery, Haley Reinhart and Mandisa are also on the Billboard 200.
