Natalie Portman Nude In New Dior Ad... But She's Not The First Celeb To Take It All Off (PHOTOS)

It's been over a year since we saw Natalie Portman's first batch of nude ads for Christian Dior's Miss Cherie perfume, and a lot has changed for the "Thor" star. First, she took home the Oscar for Best Actress for her performance in "Black Swan." Then she gave birth to her son, Aleph and later married her former choreographer Benjamin Millepied.

Now, the Academy Award-winning actress has taken it all off again, this time for Dior's "The New Nude" makeup line advertisement. The hot mama looks super sultry in the photo... and even makes us forget that this is not the first time a celebrity has gone sans clothes in the name of a brand.

Take a peek in our gallery below to see Portman strip down for Dior and keep clicking through for more celebrities, like Heidi Klum, Olivia Munn and Julianne Moore, baring skin in advertisements.
