The 22-year-old singer-and-actress experienced many ups and downs in 2014, splitting and getting back together with Justin Bieber on several occasions before seemingly separating for good late last year, reported Femalefirst.
Asked if she has learned to cope with the pressure of being a celebrity now, the 'Rudderless' star said, "I'm still young and going through the confusion women my age are feeling. Sometimes your mistakes are going to teach you more about life. I have to tell myself I can't be perfect and that I should enjoy all the good things that are happening.
