Hilary Duff's

Rumor is that she may have had breast implants and a nose job. As for breast implants, plastic surgeon Anthony Youn raised this possibility saying: “It is definitely possible she may have had a breast augmentation. The edges of her breast look very defined, which can be a sign of breast implants. If they are implants, they are not too big and tastefully done.” She probably went from a 34B to a 36C.
As for a nose job, it is clear in the before and after photo above that Hilary Duff’s previous nose was was much more bulbous and full, resulting in a younger, fluffier looking face, while her new nose is narrower and gives her a more refined look.
Hilary Duff has also has plastic surgery teeth, well not plastic surgery per se, but cosmetic dentistry in terms of veneers. Her once smaller and slightly stained smile is replaced with a broader whiter one.
Ever since her dental makeover, Hilary shows her pretty smile much more often now. She reportedly had her teeth redone after a mishap on stage with her microphone caused some chipping of her front tooth.
