NEW YORK (AP) -- "The Voice" is leaving the judging drama to its rivals.

The NBC singing contest said Friday that Christina Aguilera and Cee Lo Green will return for "The Voice" Season 5, joining Adam Levine and Blake Shelton.

Their midseason replacements - Shakira and Usher - will be back for Season 6, which will air in midseason 2014.

Meanwhile Fox is scrambling to revive "American Idol" after record low ratings for Thursday's finale, with 14.3 million viewers. Original judge Randy Jackson has already announced his exit and Fox is making yet-to-be detailed format changes.

Last week "The Voice" narrowly edged out "Idol" in weekly ratings.
