Christina María Aguilera

Aguilera confirmed she was pregnant on November 4, 2007, though Paris Hilton accidentally revealed her pregnancy several weeks prior during a party Aguilera hosted. She gave birth to her son, Max Liron Bratman, in Los Angeles, California early the following year and held a bris for Max Liron with Bratman, who is of Jewish descent, where he was circumcised in accordance with Jewish ritual. Aguilera was reportedly paid $1.5 million by People magazine for her baby pictures, which according to Forbes places fifth on the list of the most expensive celebrity baby photos.
In 2008 Aguilera appeared in the Martin Scorsese documentary Shine a Light which chronicles a two day Rolling Stones concert in New York City's Beacon Theatre. The film features Aguilera performing "Live With Me" alongside Mick Jagger. Shine a Light premiered at the Berlin Film Festival and was released worldwide on April 4, 2008. She also had brief cameo in the comedy film Get Him to the Greek, and appeared as a guest judge on the sixth season of Project Runway on Lifetime Television. She and designer Bob Mackie were the inspiration for the challenge in which they had to design a stage outfit for Aguilera. To commemorate Aguilera's ten years in the music industry, RCA Records released, Keeps Gettin' Better: A Decade of Hits on November 11, 2008 exclusively at Target stores in the U.S. The greatest hits included her first three number one singles, and other songs released from her previous three albums. "Lady Marmalade" and several Spanish singles from Mi Reflejo were included in the worldwide releases. The album's only single, "Keeps Gettin' Better", was premiered at the 2008 MTV Video Music Awards, and debuted and peaked at #7 on the Billboard Hot 100, her highest debut on the chart. Following the greatest hits, Aguilera took over a year hiatus in 2009 working on her then upcoming album and film. She was one of Billboard's Top 20 Artists of the Decade in their year-end charts.
• 2010–present: Bionic, Burlesque and The Voice
Aguilera's sixth studio album Bionic was released on June 8, 2010. The album's producers included Tricky Stewart, Samuel Dixon, Polow da Don, Le Tigre, Switch, Ester Dean, songwriters Sam Endicott, Sia Furler, Claude Kelly, Linda Perry and collaborations with M.I.A., Santigold, Nicki Minaj, and Peaches. The album's only two singles, "Not Myself Tonight" and "You Lost Me" peaked at #1 on the Billboard Hot Dance Club Play Charts but were unsuccessful elsewhere. Bionic's material consisted of many mainstream and pop records along with electronic and dance music. The album was released to mixed reviews from music critics, with Jon Pareles of The New York Times writing that the singer's new music direction "makes her sound as peer-pressured as a pop singer can be." Allison Stewart of The Washington Post described the album as being "noisy, robotic and overstuffed" and felt that one of the disc's "greatest disappointments" is its "virtual abandonment" of Aguilera's voice. She concluded that Aguilera attempts "to do it all," which was to try to "revel in her newfound domesticity, to wrest her crown from Gaga and to reestablish her sex kitten bona fides," but overall thought that the plan backfired on Bionic. Dan Martin of the NME wrote, "Perhaps best of all is ‘Monday Morning.' Written with Santigold and The Bravery’s Sam Endicott, it’s a Day-Glo disco jam that sounds like Gwen Stefani doing "Borderline". The album's sales were underwhelming in the US compared to her previous releases selling 110,000 copies in its first week landing at #3. The album has sold 270,000 units in the US to date. Shortly after the album's release, further promotion ended and a scheduled summer tour for the album was cancelled due to "inadequate rehearsal time". "You Lost Me" was her first single to not chart the Hot 100 while Bionic was her first English studio album not to receive a Grammy nomination. Aguilera responded to the album's performance in an interview saying, "I was really proud of that record. I think there was a lot of promotion issues, coming from a standpoint of how everything resulted. Nothing is ever a setback. If anything, it just motivates you for what’s next."
