Miley Cyrus insists doesn't "go around just trashing hotel rooms and partying."
The 22-year-old star - who has been criticised in the past for posing naked, risky performances and admitting to using drugs - still believes she is a good role model for her young fans.
Asked what might surprise a stranger about her, the singer, who is the new face of MAC cosmetic's Viva Glam campaign, said: "I'm not the way that people try to make me seem ... I don't go around just trashing hotel rooms and partying, that I'm actually working on, you know, music that I love and being involved in things that I love.
"I can actually say I am [a good role model] for what I know of what is important to teach people -- and what is important to teach people is that ... you can't judge other people."
The 'We Can't Stop' hitmaker is currently dating Arnold Schwarzenegger and Maria Shriver's eldest son, Patrick Schwarzenegger, but admits she can't spell his last name.
She said: "Literally, I just had this conversation, I can't tell you. Apparently there's not a T in it."
Meanwhile, the 'Wrecking Ball' hitmaker thinks Justin Bieber, who recently dyed his hair, is copying her short blonde style.
She told 'Good Morning America': "I saw him the other day and I had to say, 'B***h stole my look!' I literally said it to him and he said, 'I'm growing my hair out.' I said, 'Yeah, me, too.' It's not easy with bleach. It's harder than it looks. He said, 'How long have you been growing your hair out?' I said, 'Since I cut it in 2012.' "
