Hayden Panettiere in a gown at Cannes

Hayden Panettiere wears a fancy strapless gown that is perfectly suited to the 2009 Cannes International Film Festival. This was at the amfAR Cinema Against AIDS 2009 cocktail party, held at the Hotel du Cap on May 21, 2009. Hayden Panettiere was born in 1989, so she turned 20 the year this photo was taken.
