Great news for all the Christina Aguilera fans. The singer is pregnant with her second child, her first with fiancé Matt Rutler. However, the sad part is Christina may not be seen taking the position of judge for the upcoming seasons of "The Voice" and reportedly the producers are looking for a replacement.

Just before news of Christina Aguilera being pregnant broke out, Cee Lo bade goodbye to the hit reality show. He revealed in "The Ellen DeGeneras Show" that Usher will be replacing him.

"I'm going to continue my relationship with NBC," Cee Lo told Ellen during his interview on Feb 19. "I have a television show development deal with them as well and hopefully some other talk show opportunities for later in the year. But yeah, I'm going to miss The Voice too. So I'm not coming back, guys," he added.

"'They are looking into many options' to replace her for the hit show's 7th season," a source told Hollywoodlife.com regarding Chirstina's taking a hiatus from the show.

The source further clarified that each season of "The Voice" runs for 3 months and with the demands of newborn, Christina will not be able to give her full commitment to the season 7 of "The Voice."

"They will have to replace Christina as she will be focused on her upcoming child and will not be able to focus on the demands that The Voice puts on the judges," the source said, throwing further light on Christina's reason for leaving the show.

Inspite of the buzz that Christina will be replaced in the show, executive producer Mark Burnett evaded the topic of Christina's pregnancy during the press conference of the show. "'The hardest part [of filming] is the jigsaw puzzle of schedules' and 'no one can be permanent; it depends on their schedules'," he told reporters.

He even continued to say that replacing Christina has never come to the table.

There is still is a haze as to who will replace Chirstina, and only time will tell what decision producers of the show will take. Till then keep watching this space for further updates on "The Voice" season 6.
