The 18-year-old singer-actress may be an international star, but like most teenagers she is not always so sure of herself.
Speaking to In Touch magazine at the 2010 Jingle Ball in New York last week, she said: '[My New Year’s resolution is] to trust myself more. I second-guess myself so much, and I ask everyone around me what they think I should do.”
She added: 'Everyone should learn to be confident in their own decision-making, and follow their own hearts.'
And her rumoured boyfriend Justin Bieber, 16, could be just the person to help her fulfill her goal.
Asked about Bieber, she said: 'It's nice to have people around me who understand me.'
