Ashlee Simpson new nose and chin?

The entire world has taken note of the bump that is gone from Ashlee Simpson's nose. But what about her shorter chin? Dr. John Di Saia MD of the blog Truth In Plastic Surgery says that Ashlee may have had genioplasty. Genioplasty is augmentation or reduction of the chin and is often performed at the same time as rhinoplasty. Ashlee used to have dimpled chin and now her chin looks short and the dimple is gone. What do you think?
