Whenever Justin Bieber invokes that magic couplet, "Baby, baby, baby, oh/Like baby, baby, baby," people get crazy cracked!
Maybe it's the pitch of Bieber's voice at this particular stage of his hormonal development that drives human beings into a rabid frenzy, like high-strung German Shepherds exposed to the simultaneous screech of 1000 dog whistles.
Who knows? But whatever the cause of Bieber, the American Airlines Arena got struck with a superserious case on Saturday night. See the cut for photos of the Biebz and opening acts Mindless Behavior, Jasmine V, and Sean Kingston.
