"It's something that I didn't expect to happen so quickly," she said of her high-profile gig at the time. "It's so crazy ... I just feel so incredibly blessed."
She also recently revealed that it isn't weird for her to be working so much while she's still a teenager.
"I feel like I grew up too fast a long time ago," she told The Wall Street Journallast week for their segment "The Columnists." "Having older siblings, you grow up around adults, so you mature more quickly. I saw my sisters and parents working every day, so I was pretty much brought up to be a workaholic."
