All in the family! Get to know these stars' brothers and sisters
Hilary and Haylie Duff
"I always wanted to be like my older sister Haylie. When she learned to ride a bike, I had to as well. If she took ballet lessons, I did too," Hilary—mom to son Luca with Mike Comrie—has said. "I took singing lessons because she did. It all just got more intense until it turned into careers for both of us."
