Pregnant pop singer Britney Spears has posed nude for the cover of the August issue of Harper's Bazaar magazine.
The star, who is six months pregnant, posed last week for the cover photograph, which is in the style of the famous Demi Moore Vanity Fair cover of 1991.
Harper's Bazaar magazine said that Spears, who has black hair in the photograph, "was never more beautiful" than when the shot was taken last week.
The magazine also said: "Since word leaked out about the shoot on Monday, people have been desperate to get their hands on the exclusive photos which were posted on various web sites without permission from the magazine."
Spears is expecting her second child with husband Kevin Federline. The couple already have a nine-month-old son called Sean Preston.
