The natural beauty bared all for the sexy photo shoot to attract attention to the People for the Ethical Treatment of Animals campaign against the fur trade.

'I was a kid, a little girl, and was watching TV at home and they showed a documentary,' she said during filming.
'And in the documentary I saw how they killed little animals, like electrocuting them, drowning them, bludgeoning them.'
'I was shocked because I was a little girl, but by that moment I thought that I would never, never, never, wear fur in my life.'
During the shoot, Elisabetta also posed with one of her own adopted dogs who licked and snuggled with his mom as she lay on the floor of the studio.

Natural beauty: The model had been dating actor George Clooney for two years
Clooney's girlfriend of two years recently revealed that she has no desire to have children with the actor.
The 32-year-old, who has been dating George since 2009, says she is content with her life just how it is.
'[Getting pregnant has] never been an objective for me,' she told Italy's Cosmopolitan magazine.
'My maternal desires are fully satisfied with my dogs.'
It is a feeling shared by Clooney, 49, who has previously said he has no plans to marry again or start a family.
'I love it to bits,' she says of their relationship. 'I am happy to participate at events as the "girlfriend of."'
