Christina María Aguilera

Aguilera's first DVD live-recording from a concert tour, Stripped Live in the U.K., was released in November 2004. In light of the tour's success, another U.S. tour was scheduled to begin in mid-2004 with a new theme. The tour however was scrapped because of the vocal cord injuries Aguilera suffered shortly before the tour's opening date. In a tribute to Madonna's performance at the inaugural MTV Video Music Awards, Aguilera performed a kiss with the singer-actress at the 2003 edition of the ceremony in August. The incident occurred during the opening performance of Madonna's songs "Like a Virgin" and "Hollywood" with fellow popstar Britney Spears. Also in 2004, she hosted a Saturday Night Live episode which included a Sex & The City skit where she portrayed Samantha Jones revealing to everyone she was a man the entire time.
Aguilera later decided to embrace a more mature image; this move was met with more praise than criticism, with articles using punch lines such as "From Crass to Class." She eventually dyed her hair cherry blonde and recorded a jingle, "Hello", for a Mercedes-Benz ad. Shortly after, she dyed her hair flaxen blonde and cut it short, and took on a Marilyn Monroe look; she is one of the main proponents (along with Dita Von Teese, Gwen Stefani, and Ashley Judd) in bringing back the 1920s–1940s Hollywood glamour look. In late summer 2004, Aguilera released two singles. The first, "Car Wash", was a remake of the Rose Royce disco song recorded as a collaboration with rapper Missy Elliott for the soundtrack to the film Shark Tale. She voiced a small singing part in the film playing a Rastafarian jellyfish in the film's closing musical number. The second song was also a collaboration, but this time as a second single from one of Nelly's double-release albums, Sweat, titled "Tilt Ya Head Back". Both singles failed commercially in the U.S., but did considerably better in other parts of the world. Aguilera collaborated with jazz artist Herbie Hancock on a cover of Leon Russell's "A Song for You" recorded for Hancock's album Possibilities, released in August 2005. Aguilera and Hancock were later nominated for the Grammy Award for Best Pop Collaboration with Vocals. She helped open the 50th Anniversary for Disneyland performing "When You Wish upon a Star", and she also collaborated with Andrea Bocelli on the song "Somos Novios" for his album Amore. Aguilera began dating music marketing executive Jordan Bratman in 2002. Their engagement was announced in February 2005, and they married on November 19, 2005, in a Napa Valley estate.
• 2006–09: Back to Basics, motherhood and greatest hits album
Aguilera's fifth studio album, Back to Basics was released August 15, 2006. The album debuted at #1 in the US, the UK and eleven other countries. Aguilera described the double CD as "a throwback to the 20s, 30s, and 40s-style jazz, blues, and feel-good soul music, but with a modern twist." The album received generally positive reviews, although many critics commented on the album's length saying, "At one disc, this would have been nothing short of masterful." A review in AllMusic adds, "Back to Basics also makes clear that Stripped was a necessary artistic move for Christina: she needed to get that out of her system in order to create her own style, one that is self-consciously stylized, stylish, and sexy." The critically acclaimed lead single "Ain't No Other Man" was a substantial success, reaching #2 on the World Chart, #6 in the U.S., and #2 in the UK. Producers on the album included DJ Premier, Kwamé, Linda Perry, and Mark Ronson. The follow-up singles did very well in different regions, "Hurt" in Europe and "Candyman" in the Pacific. She co-directed both music videos, the former with Floria Sigismondi who directed her "Fighter" video, and the latter, "Candyman", with director/photographer Matthew Rolston which was inspired by The Andrews Sisters. Back to Basics has sold 4.5 million units worldwide, with over 1.7 million sold in the US.
