Natalie Portman takes off knickers to show bum in new film

Natalie Portman bares her butt in her new movie.

The actress strips off within the first few minutes of Wes Anderson’s short film Hotel Chevalier and refused to use a body double.

Mrskin.com – a website dedicated to documenting all nude film scenes – revealed: “Eight minutes in Natalie’s co-star Jason Schwartzman undresses her, finally removing her panties to show a full view of her a** and it’s all her, no body double.”

The 26-year-old star recently revealed she asked for a look-a-like to step in for her nude scene in Goya’s Ghosts.

She said: “There’s a long shot of a nude woman, but it’s not me. You do see some parts of me unclothed, but if they end up on websites making it look like I’m nude, I’m going to be really, really angry.”

Natalie played a pole dancer in her film Closer – in which she dances raunchily for Clive Owen wearing only a thong – but has denied she accepted the controversial role to rid herself of her squeaky-clean image.

The Ivy-league graduate said: “I didn’t do the scene in order to prove something. I just want to get on with my life and do what feels right.”
