Singer-actress Christina Aguilera has reportedly signed for a third series of The Voice.

According to showbizspy.com, the 31-year-old is said to play the role of mentor on the pop star search show for a third series, commanding a fee in the region of $10 mn.

It had previously been rumored Aguilera would be axed from the show as network bosses were concerned about her less involvement with show.

Aguilera has previously said she loves judging the shows, "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," she added.
