Christina Aguilera to Judge NBC's 'The Voice' Alongside Adam Levine and Cee Lo Green

For Christina Aguilera, the past few months have been filled with a series of ups and downs more dramatic than the singer's trademark vocal runs. Her feature film debut, Burlesque, was eviscerated by critics and flopped at the box-office. Then, surprisingly, the cabaret flick scored a Best Picture nod at the Golden Globes, and Aguilera herself was nominated for penning the lyrics to Best Original Song nominee "Bound to You."

February kicked off with the Grammy-winner booking a prestigious gig singing the National Anthem at the Super Bowl, a performance that was a widely-publicized failure after she botched the lyrics to the song. Then one week later, Aguilera redeemed herself with a stellar tribute to Aretha Franklin at the Grammy Awards--marred only slightly when she tripped on stage while walking out to present an award immediately after.

March hasn't been any less eventful for the singer. On Tuesday morning, Aguilera was arrested on a public drunkenness charge. But once again, good news quickly comes her way as she's just been cast alongside Maroon 5's Adam Levine and Cee Lo Green in NBC's reality competition series The Voice:

"I am so excited to be part of such a wonderful project that celebrates music and the talent behind it, she said, "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.' "

The Voice is one of three major singing competitions debuting this year as rivals to Fox's American Idol. Simon Cowell's buzzy British import The X-Factor is still on a casting search for its judging panel, while Jewel and former Idol judge Kara DioGuardi will be part of a Bravo competition for singer-songwriters. In a risky move, The Voice, which will be hosted by Carson Daly, will premiere while Idol is still on air. Here's the conceit of the show, according to The Hollywood Reporter:

During the audition rounds, the coaches sit in rotating chairs with their backs to the contestants, so they can only hear the singers, not see them. If they like the performance, they push a button, sending the contestant to the next round and claiming the contestant as one of their students. If more than one coach likes a contestant, the singers gets to choose who will be his/her coach.

Let's hope Aguilera won't be too hard on contestants for forgetting their words.
