What a year it's been for Adele!

Her CD, 21, has been a top seller; In fact it's back to number one this week.

She's been nominated for four American Music Awards.

And, she's had to cancel numerous concerts due to vocal problems.

But apparently the vocal rest hasn't helped... Her doctors are now telling her that surgery is the only option.

This afternoon, her web page posted the news: "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."

Unfortunately, it also means that she'll be missing the American Music Awards.
