she's never had any... I remember watching a doco of some sort where they showed making of king arthur
http://www.imdb.com/title/tt0349683/ promo posters, and they had to 'shop her boobs to hell. If you scan internet you could probably find some before/originals to compare with the poster releases.
and she's not ugly just because she doesnt have much boobage.
(yeas I have small boobs)
