Aguilera, Green return for 'Voice' Season 5

"The Voice" is leaving the judging drama to its rivals, The Associated Press reports.

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. 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.

According to Nielsen Co. figures Friday, Candice Glover's victory over Kree Harrison was watched by 14.3 million viewers. That's a 33 percent drop from the year before, when 21.5 million viewers saw Phillip Phillips claim the "Idol" crown. That represented the show's previous record-low finale audience.

"American Idol" saw an even steeper 44 percent drop among advertiser-coveted young adults for Thursday's finale.

The lack of interest in the winner of this year's contest parallels the show's declining ratings for the season.
