Hilary Duff: A Natural Beauty

Keeping herself in fine form, Hilary Duff was looking especially lovely as she left her West Hollywood gym on Thursday (July 9).

Showing off her natural beauty with a make-up free face, the "Cheaper By the Dozen" actress toted her favorite Prada handbag as she passed awaiting paparazzi.

Meanwhile, Miss Duff has been lining up a full schedule - as a few big announcements have been made on her behalf as of late.

Along with being nabbed to make a guest appearance on the hit CW show "Gossip Girl," Hilary was also just named as ambassador for the local youth of Bogota, Colombia.

The 21-year-old is said to be visiting the country as a guest of honor sometime between August 1st and 15th.
