If you don't have that trust in the backbone of the project, you may not know what you're making.

I'm a huge fan of the series of books by Cassandra Clare, The Mortal Instruments. I'm a fan myself, so to be cast as the lead heroine is completely incredible.

I don't wear dresses all the time - it's nice to save those moments for certain occasions and to make it feel extra special.

Celia [Brady] is a young woman who, you know, she's still got that fresh young vibe about her but at the same time she's quite wise beyond her years and very mature and she has that womanly, sexy quality, but at the same time she's very youthful in her clothes. She has that interesting mix between the two. I really love that balance about fashion.

When I first covered [presidential election ] in 2008, I was asking questions for kids around the world, but mainly for myself. I didn't know the process, I didn't know how it worked. Now, of course, I'm more schooled on it, but I deal with so much politics in my fashion work and in Hollywood, that I haven't been as connected this time.

I'm not against Twitter or Facebook. I'm not against anything. Never say never.

My advice for girls who are waiting for their Prince Charming is to be open for anything. Be open to new experiences, be open to the idea that it may take longer than you want, but if you're open to meeting new people and new adventures, then love will come along.
