Pop divas Lady Gaga and Nicole Scherzinger are among the many stars who have bared their naked bottoms for 'Culo,' a coffee table photo book that pays homage and respect to one of the most loved aspects of the female form: the derriere.

The book, 'Culo by Mazzucco,' was created by Diddy in conjunction with Interscope head honcho (and 'American Idol' mentor) Jimmy Iovine and photographer Raphael Mazzucco.

Can somebody cue the Sir Mix-a-Lot song 'Baby Got Back?' It's a fitting song for this book, which we must point out is artsy, not pornographic in its celebration of the backside. However, it still would be fun to flip through the book, which is available now, while Sir Mix-a-Lot sings "I like big butts and I cannot lie."

The book takes its title from the Italian word for "buttocks" and if not for this ambitious and artistic project, we might not have otherwise been able to take a gander at Lady Gaga's bare (and perfectly shaped) backside or Scherzinger's naked patoot. Fergie also shows off her naked butt in the book, as well.

Gaga's shot looks to be from her 'Born This Way' album shoot. She rocks a fierce pose, putting her paw up and her backside out. Nic is looking like a native with her nakedness, flowers and body paint. She hails from Hawaii and she certainly looks like a water goddess in her photo.
