The other day, Christina Hendricks said her breasts are 100% natural.  And I really, REALLY want to believe her.

Well, I think I'm starting to come around again.  Especially after seeing a photo of Christina in a black, one-piece bathing suit while on vacation in Italy.

Take a look...

(I'm no expert, but breast-watching IS a hobby of mine.  And that cleavage looks God-given.)
