Britney Spears has posed for US magazine Harper's Bazaar, appearing nude on the cover.
The star, who is five months pregnant with her second baby, is also shown lying on the floor wearing a fur coat in a shoot reminiscent of the famous Demi Moore Vanity Fair cover, 15 years ago.
The star, who is thought to be having marriage problems, recently opened up on a US chat show, telling the host that she was 'an emotional wreck' during her second pregnancy, but that her husband, Kevin Federline was a great source of support. |
