Christina María Aguilera

Aguilera confirmed news reports that she and Bratman had separated, saying in a statement, "Although Jordan and I are separated, our commitment to our son Max remains as strong as ever." Aguilera filed for divorce from Bratman on October 14, 2010, seeking joint legal and physical custody of their son, and specifying September 11, 2010 as the date of separation. They later reached a settlement agreement and custody deal, details of their agreement were private. Their divorce was finalized on April 15, 2011. The following month she appeared as herself on the Entourage season seven finale as a client/friend of Ari Gold. On November 15, 2010, Aguilera received a Star on the Hollywood Walk of Fame.
It was confirmed in 2009 that Aguilera would appear in her first feature film, the musical Burlesque, released in November 2010. She portrayed a small town girl, Ali Rose, who finds love and success in a Los Angeles neo-burlesque club. Aguilera performed eight of the musical numbers on the film's soundtrack released on November 22, 2010. Aguilera co-wrote a number of the tracks working with producers and writers including Tricky Stewart, Sia Furler, Samuel Dixon, Linda Perry, Claude Kelly, Danja, and Ron Fair. The remaining two tracks were sung by Cher, who co-starred alongside Aguilera. Distributed by Screen Gems, the film was directed by actor and director Steve Antin who also wrote the script. Antin wrote the role of Ali specifically for Aguilera. Aguilera's co-stars also included Cam Gigandet as her love interest, Eric Dane, Kristen Bell and Stanley Tucci. Several critics praised Aguilera's performance. A review in TIME states, "Aguilera might not be to your taste, or mine, but in terms of sheer power, she's impressive. If Ali were real, she'd have already been discovered on American Idol." While Variety wrote, "Aguilera, while undeniably entertaining when her character is onstage, cannot spin the slight backstory into anything resembling a full-blooded person." Though Burlesque was released to mixed reviews from critics, the film received a Golden Globe nomination for Best Picture - Musical or Comedy and earned Aguilera, alongside co-writer Sia Furler and writer/producer Samuel Dixon, a nomination for Best Original Song for the track "Bound to You". However, she lost to the film's Diane Warren penned "You Haven't Seen the Last of Me" which was performed by Cher. Burlesque has grossed over $90 million worldwide.
Following the release of Burlesque, Aguilera collaborated with rapper T.I. on the track, "Castle Walls" which is included on his album No Mercy. Aguilera performed the U.S. national anthem, "The Star-Spangled Banner", during the Super Bowl XLV on February 6, 2011 and created embarrassment when she omitted a line of the anthem and messed up the song's lyrics. She later apologized, telling CNN that "I got so caught up in the moment of the song that I lost my place. I can only hope that everyone could feel my love for this country and that the true spirit of its anthem still came through." The following week, Aguilera, alongside Jennifer Hudson, Martina McBride, Yolanda Adams, and Florence Welch opened the 53rd Grammy Awards paying tribute to Aretha Franklin. Aguilera began dating musician and production assistant, Matt Rutler who she met during the filming of Burlesque. Her personal life was the subject of scrutiny and reports over out of control behavior, excessive drinking and a reported confrontation with her co-star Julianne Hough. On March 1, 2011, Aguilera was arrested for public intoxication in West Hollywood as her boyfriend was arrested for DWI. According to a Sheriff's spokesman, Aguilera "was not capable of taking care of herself. She didn't really understand where she was, she didn't even know where she lived." She was later released on bail and no charges were filed. Although the L.A. Sheriff's office stated Aguilera's mug shot would not be released to the public, E! News obtained the mug shot which circulated social networks and the media shortly after her release. Rutler's DWI charge was dismissed due to insufficient evidence, after his BAC at the time of arrest was determined to be at .06%, below the legal limit in the state of California. Aguilera signed to become a coach and judge on the John de Mol created singing competition The Voice. The show will air on NBC in late April, and will also feature musicians Adam Levine, Blake Shelton and Cee Lo Green as judges and coaches; as well as host Carson Daly.
