Justin Bieber performed at the second night of the KIIS-FM 2012 Jingle Ball, held at the Nokia Theater in Los Angeles, on Dec. 2. Alicia Keys actually came on stage to announce him alongside Ryan Seacrest, and at that very moment, the screams were deafening. Our ears are still ringing. Imagine if you were there live! Your ears would be hurting. But it was worth it, since The Biebs turned in another winning performance.

It was a parade of hits, where he performed new 'Believe' songs like 'Beauty and a Beat' and 'All Around the World,' the latter of which kicked off his set, to the delight of shrieking Beliebers who were in attendance.

Wearing a black tee and jeans, and a gold chain, The Biebs was all swag, swag, swag, dancing his face off. He was wearing a black hoodie, too, which he promptly removed. Nicki Minaj wasn't there to accompany him on 'Beauty,' though. Her parts were piped in via tape.

He also performed 'Be Alright.'

When The Biebs sat next to his acoustic guitarist for 'Fall,' the Beliebers sang along in unison. They were his choir, and they seemed to be happy about it.

In other JB news, The Biebs and his girlfriend Selena Gomez also offered more proof that they are still together or back together by taking a ride in a white Ferrari together. What, the tricked out, chromed Fisker Karma isn't good enough anymore? Nevertheless, the Ferrari is a sweet set of wheels, and the duo being snapped together in this ride "fuels" rumors that they are back together. That is, if they ever even broke up.
