Christina Aguilera has been added to the coaching ranks on NBC's upcoming show The Voice, the network announced Wednesday.

"Her journey as an artist, who started so young in the music business, will be an inspiration to the talent she coaches on the show," network executive Paul Telegdy said in a statement.

The five-time Grammy winner, who appeared on Star Search at age 9, becomes the third coach for the show after Cee Lo and Adam Levine. A fourth remains to be chosen.

Aguilera said she's looking forward to "the opportunity to help shape new artists' careers and mentor them."

It's already been a turbulent year for the 30-year-old singer, who rose to stardom in 1999 with hits including "Genie in a Bottle" and "What a Girl Wants."

Last month, Aguilera flubbed her lines while singing the national anthem before Super Bowl XLV. Days later she tripped on stage at the Grammys. A week after that, Aguilera finalized her divorce from her husband of five years, Jordan Bratman. And just on Tuesday, she and new boyfriend Matthew Rutler were arrested on suspicion of public intoxication.
