I`m not perfect: Selena Gomez

London: Singer-actress Selena Gomez never wants to be a role model because she considers herself imperfect and describes her job as "superficial".

"I never really said I want to be a role model. But then when it happened I was so down for it," a website quoted Gomez as saying.

"I`m human, I`m not perfect. I make mistakes all the time, but I guess my job is to keep those mistakes to myself, which I`m already fine doing and just try to be the best I can be for those kids," she added.

The 18-year-old, who is recovering from a spell in hospital for "malnourishment" and exhaustion, also said: "This is a very superficial job. I sit in a chair for two hours and get hair and make-up done and talk about myself in interviews. That`s a very vain thing to do. And I do get caught up in it sometimes."
