His voice didn't crack! Well...that much. Here is Justin Bieber performing "Baby" at Wango Tango, where he added a new rap.
Props to the person for not keeping a steady camera for most of the performance even with the madness....er...I mean fever going around.
In other news, Twitter took Justin Bieber off as a trending topic, which did not sit well with the Biebs. It had to be done Justin. Your just too much for all of us. Ahem. yea, right. Enjoy the clip.-Dr.FB
