There are a lot of reasons I like Natalie Portman, not least of which is the fact that she rarely seems to wear a bra. It's not a big thing, but there is definitely something sexy about a girl who doesn't. Add to that the inherent sexiness of being Natalie Portman, and, well, that's one damn sexy combination.
And while these pictures aren't quite as good as those from last week featuring a blonde, and very nippy Natalie Portman, she is, as previously stated, not wearing a bra, and, she's gone back to her natural (but actually dyed) dark hair. Oh, did I forget to mention that?
