Adele's '21' earns best sales year since Usher's 2004 album

Grammy Award-winning singer Adele's album "21" sold more copies in one year than any other artist in seven years.

According to Reuters, "21" sold over 5.6 million albums stateside since its release in January, which is more than any other album released in the U.S. in 2011 and the first album to cross the 5 million mark since Usher's 2004 album "Confessions," which sold a whopping 7.9 million units.

Adele released two singles from the album, "Rolling in the Deep" and "Someone Like You" and cancelled numerous shows due to vocal cord ailments.

The British singer took home two American Music Awards on November 20, for Favorite Pop/Rock Female Artist and Favorite Album ( See a full list of winners).

Adele recently took t! o her bl og to tell fans she's "doing really well" after undergoing surgery on her vocal cords to stop a reoccurring condition on November 7.

"Thank you for all your positive thoughts and get well wishes. I'm doing really well, on the mend, super happy, relaxed and very positive with it all," the 23-year-old singer wrote on November 14. "The operation was a success and I'm just chilling out now until I get the all clear from my doctors."

A spokesperson for Massachusetts General Hospital told the Associated Press that the British songstress underwent vocal cord microsurgery to stop recurrent bleeding from a benign polyp. The condition is usually the result of unstable blood vessels in the vocal cord that can rupture.

Adele first announced the news of her surgery on October 28. "It is with deep regret that Adele has been forced to cancel her remaining live dates and promotional appearances in 2011," read a statement from Adele's official website. "She is to undergo surgery to alleviate the current issues with her throat and a full recovery is expected. As a result, doctors have ordered her to rest her voice and completely recuperate before looking to schedule any work commitments."

Previously the singer's spokesperson had to deny rumors that the singer was suffering from throat cancer. Her spokesperson told People magazine, "We would like to reiterate that Adele is to undergo su! rgery fo r a hemorrhaged vocal cord." The statement went on to say, "All reports regarding any other condition are 100 percent false."
