George Clooney’s leggy girlfriend Stacy Keibler and FERGIE are among the stars showing off their butts in a cheeky new book by photographer Raphael Mazzucco.
Victoria’s Secret stunner Alessandra Ambrosio, pop star Nicole Scherzinger, singer/songwriter Sarah McLachlan and Pamela Anderson also feature in Culo by Mazzucco, which features naked rear shots the snapper has taken over the past decade.

Mazzucco admits many of the shots were taken during spur-of-the-moment shoots: “Each picture and the nature of the shooting was in so many different places in the world, so a lot of the photographs are very spontaneous and we just went with that.”

Keibler appears twice in the picture book – in one shot she’s standing, facing a wall while gold paint is thrown at her; in the other she’s reclining covered in black paint.
