The 16 year old admits she struggles to trust potential suitors due to her fame and fortune, and asked showbusiness veteran Moore for advice on how to choose the right guys.
She tells Britain's InStyle magazine, "You think, 'Who's out to deceive me?' That's hard. Especially growing up and liking guys and, maybe, 'Do you want to be in a relationship? Is this person trying to be in my life because I'm famous?' You can't just like someone. They might be using you.
"I talk to Julianne (Moore) about it and she says, 'Look, just be careful. Trust your judgement but don't get in too deep sometimes.' Because, you know, when you're young, you fall in love and don't know it's happening."
