It's a Christmas miracle: Justin Bieber told an LA radio station yesterday that he's retiring after his new album comes out next week, the Huffington Post reports. "I'm actually retiring, man," Bieber said. "I'm just gonna take some time. I think I'm probably gonna quit music." But, bah humbug, members of his entourage tell TMZ the singer was joking. "The kid's got ambition," says one of Bieber.
