What do I do.?? Please help me out..?

Ok, I want to be just like a regular singer like Justin Bieber, Greyson Chance, etc. But I am not gunna sing about drugs, sex etc. Could I get signed into that kinda music singing positive music if im a good singer, entertaining, and I already have alot of fans? I would sing good songs and stay most christlike I could. I just would really like being in the music business like Justin Bieber because it seems like more fun. I really wouldnt have a problem being a christian singer, but I dont know if I would have more fun doing it. My question is, Could I be in the business with Justin Bieber, Greyson chance, bruno mars, ya know what im talking about, etc. Singing good music, UNLIKE like lil wayne and somewhat Bruno Mars, because they sing about sex and who knows what else. Please Help Me Out..... Thanks!!!
