tattoos new testament

Christian bands and tattoos?
I am a born again Christian and I believe it is wrong for Christians to have tattoos. In the Old Testament states that do not pollute own body and although I can not remember anything in the New Testament about the brand of our own body, I think it is wrong because our bodies are a temple for the Holy Spirit. Many Christians that this too, but then why do many members of the Christian band there have tattoos? There are few, but the only I can think of at the top of my head is red. I only listen to Christian music on my ipod and stuff, and while I'm always looking for new Christian bands and songs, I think a detour when I see a Chrisitian band members with tattoos. Is there any reason why this is? Do people agree that it is a kind of bad things about them to do this? Is it perhaps because he has tattoos before they were saved?
God cares about the inside, not outside, he said, "the judges of man in the appearance but God looks on the heart. "
