Hilary Duff Flips The Switch

Hilary Duff flips the switch at the lighting ceremony at the Empire State Building on Thursday (May 14) in New York City.

The world-famous spire shined red to kick off the AIDS Walk weekend and to honor those fighting to stop and prevent HIV/AIDS.

On Sunday morning, May 17, the Duffster will also co-host the AIDS Walk Opening Ceremony in Central Park, and will then walk with her team “Hilary Duff — Walk with Love.”
