Hilary Duff: LA Times Festival of Books!

Hilary Duff takes part in the Los Angeles Times Festival of Books on Saturday (April 30) in Los Angeles.

The 23-year-old actress and author signed copies of her very first novel, Elixir, in a booth at the book fest at USC.

Late last month, Hil and her big sister, Haylie, helped feed those in need at the Los Angeles Mission before Easter Sunday.

Before serving Easter dinner at the Mission, Hil and Haylie were spotted going shopping at Bed Bath and Beyond together.
