Soul diva Joss Stone has been drinking alcohol since she was 13, and blames her boozy habit on being British. The pop star, who now resides in America, fears losing her powerful voice but can't resist having a sneaky drink when she is back in her homeland. She says, "I've been drinking beer since I was 13. I'm English! Sometimes I smoke, sometimes I drink. But I don't go on binges. "I'm not a genuine bad girl. I don't want to ruin my voice. "But when I'm home in England, I have a beer and a smoke. Sometimes I even smoke weed."
