Hollywood starlets Hilary Duff, Haylie Duff and Selena Gomez flashed their lovely smiles for shutterbugs at the 5th Annual Runway For Life event, which benefits St. Jude Children's Research Hospital.

The trio showed up to the fashion show to support the great cause -- all three looking stunning and radiant. Both Hilary and Selena donned black cocktail dresses, while Haylie shook things up with an elegant, sparkly top.
