Justin Bieber may be closing in on the big 1-8, but he says his lyrics won't be changing anytime soon.

The singer says he won't be doing any songs about drinking or partying, because he wants to emulate his idol Michael Jackson, although he's considering writing songs about "making love".

Bieber told V magazine, "I'm not going to try to conform to what people want me to be or go out there and start partying, have people see me with alcohol... I'm never going to make myself so the kids and the parents don't respect me... I want to be able to do what Michael did - he always sang clean lyrics - and it was always that little kids loved Michael and grandparents loved Michael.

"I don't want to start singing about things like sex, drugs, and swearing. I'm into love, and maybe I'll get more into making love when I'm older. But I want to be someone who is respected by everybody."
