PHOTOS: Justin Bieber Gets Ready To Rock Out The VMAs

Justin Bieber is leaving nothing to chance with his MTV Video Music Awards debut Sunday night. The teen sensation spent hours rehearsing on Friday, as seen in these pictures obtained by RadarOnline.com.

Bieber will make a grand entrance into Nokia Theatre LA Live in a bright red convertible and streets in downtown L.A. were actually blocked off for the rehearsal!

Bieber Fever continued into the Theatre where he rehearsed a comical bit where he and his band get tangled in dozens of cables.

Don't be surprised if The Biebs steals the show, Sunday night at 9 pm on MTV.
