Notch up yet another new identity for Madonna: children's book author.

No, this will not be a G-rated version of her notorious early '90s pictorial book "Sex," but a spiritual book for youngsters, she reveals in a new interview with Vanity Fair magazine.

Continuing along this new pure path, the magazine says the pop star, 44, is strumming Cat Stevens' "Morning Has Broken" on her acoustic guitar at least once a day, practicing yoga and cutting the erotic scenes out of her upcoming movie.

As for the children's book, Madonna describes it as a collection of allegorical tales for 5- to 8-year-olds that she assembled with her British movie-director husband, Guy Ritchie, 33. (They have a 2-year-old son together, Rocco, and Madonna is also the mother of a daughter, Lourdes, 5.)

"Hey! Nothing is what it seems," the author tells Vanity Fair, noting that before the birth of Lourdes, she had been living in a very "me-me-me universe."

She also claims to have had Ritchie tone down the sex scenes in their upcoming movie "Swept Away," which is about a repressed upper-class woman who gets down and dirty when stranded on an island with a lower-class sailor.

"I'd like it if people liked it," Madonna says about the movie, which has been getting a decidedly mixed reception at preview screenings. "But I'm not going to slit my wrists if they don't. Especially because it's a labor of love between me and my husband."
