Singer Christina Aguilera, who is expecting her second child, has stripped down to pose in her pregnant form.

The 33-year-old, who is due to have a baby girl this time, is loving her changing body and she has appeared completely naked for V Magazine, reports dailymail.co.uk.

In one image, which released online Friday, the "Beautiful" singer is seen standing against a white background making the sole focus of the photograph her heavily pregnant body.

Aguilera has used hand to cover one of her breasts and she has placed the other hand above her head, from under which her long blonde hair cascades down her back in waves.

Explaining why she wanted to immortalise her pregnant form, she said: "As a woman, I'm proud to embrace my body through all stages of life, staying fearless and confident in surrendering to the unknowns the future has in store."

The singer and her fiance, Matthew Rutler, 28, are likely to become parents this month.

Aguilera already has a six-year-old son Max with ex-husband Jordan Bratman. In 2008, she had also stripped down for Marie Claire while pregnant with Max.
