The 26-year-old 'Bang Bang' hitmaker said she liked to offer support and advice to other artists because it is not easy being in the public eye, reported Contactmusic.
"We've all been there. And I know how hard it is. Until you're famous and you go through what we go through, you can't understand. No-one understands. I think that it's important for people that are in a similar situation to help each other out, when it's tough, so that's how I am as a person.
