Justin Bieber, Believe
Fresh off his 18th birthday, the teen-pop idol is gunning for Justin Timberlake on his third full-length LP, which he's cutting in Los Angeles. Kanye West and Drake are reportedly among the disc's all-star guests; producers include Diplo, who recently spent four days with Bieber crafting uptempo, Jackson 5-ish tracks. Says the producer, "Everybody wants to be on this."
