Christina Aguilera Has Joined "The Voice"

Christina Aguilera is coming to NBC.

The five-time Grammy winner singed on as a coach/judge on Mark Burnett’s singing competition series The Voice.

That makes three spots on the show filled by celebrity singers so far, with Xtina joining Cee Lo Green and Adam Levine. Aguilera was first reported as in talks for the show exclusively by EW last week.

“I am so excited to be part of such a wonderful project that celebrates music and the talent behind it,” Aguilera said in a statement. “To be given the opportunity to help shape new artists’ careers and mentor them to see their dreams come to fruition is a task I welcome with open arms.I am so happy to be working with fellow Grammy Award winners Adam and Cee Lo as I feel there is so much we can all bring to The Voice.”

Though launching any music competition series at the same time Fox’s American Idol is on the air remains perilous, the lineup gives NBC some heavy hitting star power behind its show — and adds to Burnett’s impressive roster of reality casting coups (anybody who can sign Sarah Palin and Christina Aguilera for reality shows is a casting wizard).

“When I decided to produce The Voice, I immediately knew that my first choice for a female coach had to be Christina Aguilera,” Burnett said. “Christina has a perfect voice and is an undeniable force in the music business. She is the epitome of The Voice.”

That Aguilera has been all over the news lately — and not for her singing — doesn’t exactly hurt the show’s prospects either. Aguilera’s recent arrest for public drunkenness, stumbling onstage at the Grammys and botching the National Anthem at the Super Bowl is the kind of unpredictability that makes for must-watch reality TV (see, Paula Abdul on American Idol).

The Voice premieres on Tuesday, April 26.
