V Exclusive! 2 Chainz, Kendrick Lamar & More Perform at Power 106's Cali Christmas 2012 (VIDEO)

Power 106's annual Cali Christmas always promises one of the best lineups of the year when it comes to hip-hop & R&B. 2012's headliners included Kendrick Lamar, 2 Chainz, Big Sean, Maybach Music Group's Rick Ross and Meek Mill, as well as The Weeknd, Clyde Carson and Ca$h Out. If that wasn't enough to make everyone loose their mind with a good time, several surprise guests jumped onstage throughout the night.

Lil Wayne and J.Cole came out to perform "Nobody's Perfect" and "No Worries," respectively, with Kendrick Lamar, who was also joined by his Black Hippy/TDE crew -- Jay Rock, ScHoolboyQ, Ab-Soul. Proving that their mamas raised them well, the new school of hip-hop didn't forget it's roots. Veteran hip-hop OGs E-40, Too $Short and Problem also came out for a group rendition of E-40's "Function." Fresh off inking a deal with Def Jam, Atlanta MC Trinidad James gave a big middle finger to all the haters out there and rolled up on a shiny three-wheeler to perform his staple "All Gold Everything." (He later donated the manually powered lowrider to charity.) To say the least, it was action packed, and VIBE TV was there to catch all the action.
