Justin Bieber has called "Boyfriend," the first single from his forthcoming album Believe, "hater-proof." But how can a song that begins with Bieber rapping, in his thickest patois, about his "swag" not be hater-bait? With a taut, funky beat by Mason D. Levy and Mike Posner, and a lyric that mixes kiddie-movie references ("I could be your Buzz Lightyear"), chivalry ("I can be a gentleman"), and hip-hop braggadocio ("Chillin' by the fire while we eatin' fondue"), the song is expertly calculated to ease The Biebs' transition from tweenpop dreamboat to... post-tweenpop dreamboat. The subtext is clear: Justin Has Actually Had Sexual Intercourse—But He Won't Harm Your Nine-Year-Old. "Hater-proof"? Try foolproof.
