The 19-year-old actress and singer told People magazine that she's either perceived as too fat or too thin in the media, which she says can be "judgmental and mean."
"And if you don't like the way you look or feel insecure, when people say things about you — in magazines or just in everyday life they can be hurtful ... But you'll never make them happy," she told the magazine.
She told People she doesn't like to discuss relationships.
"It's not my job to talk about my relationship," she said. " ... But the more you try to keep it quiet, the more people want to know about it."
