Usher and shakira to join the voice

If you thought there was a lot of shuffling going on in the Reality Singing Show world then this story is going to fit right in.  The hit singing competition, The Voice, not to be outdone by the X-Factor and Idol refreshing their judges is replacing C-LO Green and Christina Agulara next season.  Now the show is saying that they are only being temporarily replaced because of commitments that the artists have outside of the show.  The other judges are staying in the lazy Susan chairs for the time being.  So Brendan Spaar has a question for you:  Is the show toying with new judges with an out in case it doesn't work or are C-LO and Christina actually the only judges on the show with day jobs?
