Billy Joel has had surgery to replace both of his hips.
The singer is said to be recovering well after the operation, according to his spokeswoman Claire Mercuri.
He had both hips replaced last week (beginning November 15) to correct a congenital condition, reports People magazine. Mercuri did not comment on when he would return to touring.
Joel recently promoted his documentary The Last Play At Shea, about his 2008 concerts of the same name. A greatest hits album entitled 'Billy Joel: The Hits' was recently released in the US to mark the 40th anniversary of his first solo album.
The record features 19 tracks including 'Piano Man' and 'New York State Of Mind'. A UK release date is yet to be set.
