Britney Bares All For Harper's Bazaar

(CBS)  In a TV interview that aired earlier this month, Britney Spears told Matt Lauer that she and her family "just need privacy."

But that didn't stop Spears from baring it all — literally — for the August issue of Harper's Bazaar, which hits newsstands next month.

The magazine cover and photo spread, shot June 22 by fashion photographer Alexi Lubomirski, features photos that are reminiscent of Demi Moore's notorious Vanity Fair cover from August 1991, in which she posed very pregnant and completely nude.

The cover photo is the only shot the magazine is officially releasing, but other shots have surfaced on several blogs without permission from the magazine.

One of those photos features a newly black-haired Spears posing with her 9-month-old son Sean Preston while wearing a long black gown. Another shows Mrs. Kevin Federline provocatively lying on the floor, completely exposing her burgeoning belly while wearing a shearling-like coat and a white string thong. Yet another has her kneeling on a stark floor, holding her breasts and wearing nothing more than a gigantic diamond necklace.

Spears was first spotted last week with jet black hair, a drastic change from the bleached blonde locks she sported in her interview with Matt Lauer which aired June 15.

The domesticated pop star spoke with Lauer about paparazzi and addressed reports that her marriage to Federline, an aspiring rapper, is on the rocks.

The interview took place at Spears' home, and the pregnant singer cried when Lauer asked her what she would say to the paparazzi who hound her constantly.

"I would just say, 'You have babies at home, and you have a wife, and if you don't, you have to realize that we're people and we just need privacy and we need our respect and these are just things you have to have as a human being.' "

She admitted to doing her own laundry, cleaning and cooking. "I still walk out of my house in rollers," she said. "I do not care what people think."

Spears said she wants the sex of her baby to be a surprise when she delivers in the fall.

The new issue of Harper's Bazaar will be available July 25.
