The 17-year-old singer-and-actress - who appeared in her first commercial when she was just three years old - believes she has learned more about herself and her career as she has got older.
She said: "You get more insight as you get older, on everything.
"I kind of woke up one morning and was like, 'Oh I see what's happening, I get everything.'
"I woke up and was like, 'I get it, I'm a product.' "
The Pretty Reckless singer - who achieved widespread fame aged 14 after starring in US drama series 'Gossip Girl' - wasn't prepared for fame but insists she doesn't worry about living her life in the spotlight or what other people think of her.
She added: "Fame just kind of happens overnight. No one prepares you for it. On 'Gossip Girl', I was just going to work, doing what I've always done, and then all of a sudden you're like, 'Woah!'
"But you get used to it. You ignore it - because whatever people say about me doesn't bother me at all. If you're in high school or college or at work, someone's not going to like you. It's inevitable. But it doesn't mean anything."
