As mentioned in the Christina post yesterday, T.I.’s No Mercy (formerly titled King Uncaged) will make its way to music outlets on December 7. Along with a Christina Aguilera guest appearance, will be Eminem, Kanye West, Chris Brown and The-Dream. Production will come from popular producers such as Danja, Dr. Luke, Jim Jonsin plus more.

What happened to the Lady GaGa collaboration? Oh that’s right, they probably realized that it was pure foolishness only done for popularity. We’ll save our full opinion for when we listen to the album but Dr. Luke and T.I.? Who would have thought…

Be sure to check out the video for the Chris Brown collaboration, “Got Back Up,” after the jump. It’s another simple affair from the southern rapper.
