Vocal lessons for a 14 year old guy?

My dream is to be the singer for a band, and I want help, I know drums and guitar so I can get those spots also, but I love to sing. Should I take vocal lessons, I have a deviated septim in my nose so I mis pronounce so letters, like n's but should I take vocal lessons or not. I want to sing like jared from 30 seconds to mars or Billy from Green Day. I know I sound like a homosexual (not sexist or prejudice against gays) but I just like to sing ya know?
