Christina Aguilera slams adam Levine on The Voice season premiere!

Season two of The Voice premiered last night after the super bowl and there was more competition between coaches HYPERLINK "" Blake Shelton, HYPERLINK "" Cee Lo Green, HYPERLINK "" Adam Levine and HYPERLINK "" Christina Aguilera than there was in that football game! Adam and Christina are known for their bickering, but last night it came to a head! The argument? Who is more self-centered. Christina calls Adam a wannabe-Justin Timberlake and a used car salesman.
