• "I love being the tough girl! And if people want to think that, that's cool. It probably has a lot to do with my voice being sort of deep. Even my mom thinks I'm my brother sometimes."
• "I hated modeling. It’s really cutthroat. My sister was the one who originally talked me into it, and I thought maybe it would be fun to travel."
