Christina María Aguilera

At the 49th Grammy Awards, Aguilera again won the Best Female Pop Vocal Performance for "Ain't No Other Man". She made a noteworthy performance at the ceremony paying tribute to James Brown with her rendition of his song "It's a Man's Man's Man's World". In January 2007, she was named the 19th richest woman in entertainment by Forbes, with a net worth of US$60 million. Aguilera performed "Steppin' Out With My Baby" with Tony Bennett on his NBC special Tony Bennett: An American Classic and on Saturday Night Live. They performed at the 59th Primetime Emmy Awards where both specials received Emmys. "Steppin' Out" was nominated for Best Pop Collaboration with Vocals at the 50th Annual Grammy Awards.
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.
