Britney Spears is preparing herself to pose naked for Vanity Fair magazine for $3 million, just weeks before she will give birth to her first child.

The Vanity Fair editors are hoping to photograph the pop singer in her seven-month of pregnancy and to publish the pictures before she gives birth in autumn.

A source revealed: "Negotiations have been in progress for a while and both sides have come up with a figure agreeable to both parties. It's a huge amount of money". The source added: "Britney just loves being pregnant and her new body".

Britney Spears follows Hollywood actress Demi Moore who posed for the cover of Vanity Fair magazine while she was pregnant in 1991.
