Haylie: Our parents used to call us Juicy and Yummy. Hilary was Juicy, I was Yummy. As we got older, Hilary became Clean Cat and I became Dirty Dog because Hilary is neat and I am messy.
Haylie: Hilary and I get along so well, it's sick. Every chance we get, we spend time together.
Haylie: (rehearsing for Hairspray, trying on her finale dress for the first time.) So, am I going to be flashing people?
Haylie: (on 7th Heaven's, second, Series Finale) There is a lot of resolution, and a lot of new beginnings, as well. A show that will go down in history.... Everyone's experience was so wonderful and we took away from it everything we wanted to, which I think is special and important.
Haylie: Most of my friends are not actors. When guys break up with them or they have any kind of rejection, it’s like this huge ordeal and they want to cry for days about it. For me, I learned rejection at 11 and 12 years old and so did my sister. The first audition you go on, you don’t get. That’s when you learn that. You learn how to deal with rejection. So that’s been one of the most positive lessons that I’ve learned.
Haylie: I feel that a lot of girls probably feel this way: there can be a role that you can act the hell out of and because they might have some previously set opinion of who you are or what you are, it makes it hard for them to see you as anything else.
Haylie: Naturally, everyone thinks siblings would be jealous over each other and fighting, but my dad always said, "If you ever fight over a part or cry over a part, you guys have to come home!".
Haylie: (On her crush on Josh Hartnett) I will marry him someday!
