Christina Aguilera has reportedly re-signed for a third series of 'The Voice'.

The 'Beautiful' singer is said to have committed to be a mentor on the pop star search show for a third series, commanding a fee in the region of $10 million, according to website TheWrap.com.

It had previously been rumoured Christina would be axed from the show as network bosses were concerned about how committed she was.

'The Voice' - where judges choose which acts to coach without seing them - has become network NBC's highest-rated show outside of NFL broadcasts, and its second series premiered on Sunday (05.02.12) straight after the Super Bowl.

All four judges from the first series -

Christina, Cee Lo Green, Adam Levine and Blake Shelton - have returned for the current second series.

Speaking about the possibilty of a third series, a source said: "We're really pleased with the entire cast. You look at the ratings and it's no accident."

A source close to Christina claims she has signed on to film the next series from September to December, but an NBC spokesman said no decision has been made about when the show will air.

Christina has previously said she loves judging the show because it is very positive toward its contestants.

She said: "There is no good and bad. This isn't about tearing people down. I want to bring these people up.

"Instinctually, you can judge people based on the way they look. I love that fact we get to sit here with our backs turned away from these people, I'm looking forward to getting moved."
