Katherine Heigl often makes the "best of" plastic surgery lists. Mostly because her breast implants look so real, and fit her frame so well, that no one is completely certain they’re fake. This before and after picture seems to put an end to the discussion about whether Katherine Heigl has breast implants. Then again, in the before picture, where Heigl's bra size is significantly small, she is is also quite young. So, the debate continues.
