Christina Aguilera is Ready to Fight on The Voice

The Voice attracted 11.8 million in a strong debut last week as Christina Aguilera, Maroon 5's Adam Levine, Cee Lo Green and Blake Shelton started picking singers in a blind audition to form teams of eight.

"We definitely fight for certain contestants," Aguilera said recently. "If [we] turn our chairs around at the same time, then we become on the hot seat. And there has been some pretty heated debates about who gets the person on their team. It's pretty addicting thus far!"

After some nail-biting auditions landed each coach with three singers, the four complete their teams Tuesday night.

As executive producer Mark Burnett tells PEOPLE, "They are all competitive and this show is like the singing version of the NBA Draft if you gave the players the power to choose their teams. Once Christina, Cee Lo, Adam or Blake press that button and turn their chair to indicate, 'Hey, I want you on my team,' but more than one turns around, the power shifts to the singer."

Next week, the coaches will tap their friends to help prep their teams for vocal battles.

Aguilera will bring aboard singer-songwriter Sia Furler; Green will consult with singer Monica; Shelton will have his pal Reba McEntire; and Levine will enlist Maroon 5's music director, Adam Blackstone. After four weeks of battles, the teams will then vie live for public votes.

Christina Aguilera's BF's DUI Charges Dropped

Christina Aguilera's week just keeps getting better.

Two days after her divorce from Jordan Bratman was finalized, the L.A. County District Attorney officially rejected the DUI case against her current boyfriend, Matthew Rutler, citing insufficient evidence.

(Rutler, 25, was pulled over and arrested in March on suspicion of DUI; Aguilera was booked on a misdemeanor charge of public intoxication.)

Law enforcement officials tell TMZ that Rutler's blood alcohol content was ultimately determined to be .06 at the time of his arrest, which falls under California's legal limit to operate a vehicle, .08.

Aguilera recently opened up to Us Weekly about her troublesome year, which kicked off when she flubbed the lyrics to the National Anthem during the Super Bowl.

"It's a life-uprooting time and there have been hiccups along the way that unfortunately the whole world gets to witness and judge," The Voice judge, 30, said. "In light of the past year, there have been obvious setbacks. I've gone through a really hard divorce, and anyone who has gone through a divorce will speak about how hard the journey is from start to finish."

Christina & Jordan Bratman's Divorced Finalized

It was beautiful while it lasted.

After a mandatory six-month waiting period, Christina Aguilera and Jordan Bratman's divorce was finalized Friday morning, court records unearthed by E! News confirm.

After separating in September, Aguilera, 30, filed for divorce from music producer Bratman, 32, in October. The duo share a 3-year-old son, Max.

Last fall, the star rebounded from Bratman with Matthew Rutler, a set assistant she met while making Burlesque.

But even with a cute new guy at her side (they're still together), the former teen pop sensation famously unraveled in a series of very public missteps in early 2011: She flubbed the the National Anthem during the Super Bowl, nearly fell offstage at the Grammy Awards, was arrested for public drunkenness and more. (An insider told Us Weekly that she crashed Jeremy Renner's 40th birthday bash in February -- and was so drunk that she passed out in his bed.)

Those recent embarrassments are now behind her, Aguilera insisted recently as she promoted her new gig on NBC's singing competition The Voice.

"In light of the past year, there have been obvious setbacks," she told Us Magazine last week. "I've gone through a really hard divorce, and anyone who has gone through a divorce will speak about how hard the journey is from start to finish."

"It's a life-uprooting time and there have been hiccups along the way that unfortunately the whole world gets to witness and judge," she added.
