Here is a quick translation of
THIS ARTICLE from "Aftonbladet"
"A close source to the founder of Playboy, Hugh Hefner, reveals that it's true. Britney will get 30 mil SEK (about $4 mil) to show herself naked. Playboy and Hefner have tried to get her to sign up since January. And now she's finally agreed. Naked skin is nothing new for Britney, but so far she has always kept atleast something for the imagination. She has always admired Madonna, who did her book "Sex" were she was naked on almost every page. So maybe it's not such a big surprise that Britney now choses to strip naked"
Or something like that
Sorry for the bad english...
