Natalie Portman Pops Off Her Top for Dior

When you've already shown off your bottom, this certainly seems like the next logical step.

Wearing nothing more than a little black headband, Natalie Portman poses topless in a new perfume ad for Miss Dior Chérie while serving up her best come-hither stare.

The actress has been getting a lot of attention lately, what with all the praise for her sure-to-be-nominated-for-an-Oscar performance in Black Swan as well as the recent news of her engagement and pregnancy.

But, hey, a little extra, er, exposure can't hurt. Especially when it looks this good, right?
