Christina María Aguilera

Ricky Martin asked Aguilera to duet with him on the track "Nobody Wants to Be Lonely" from his album Sound Loaded; released in 2001 as the album's second single. The single reached number one on the World Chart and top ten in several countries. In 2001, Aguilera, Lil' Kim, Mýa, and Pink were chosen to remake Labelle's 1975 single "Lady Marmalade" for the film Moulin Rouge! and its soundtrack. The song peaked at number-one on the Billboard Hot 100 for five weeks and was the most successful airplay-only single in history. It also reached number one in eleven other countries and earned all four performers a Grammy Award for Best Pop Collaboration with Vocals. Aguilera's appearance in the music video was compared to that of Twisted Sister frontman Dee Snider. The video won two MTV Video Music Awards including Video of the Year in 2001, where Aguilera accepted the award saying, "I guess the big hair paid off."
That same year, the single "Just Be Free" emerged into record stores which was one of the demos Aguilera recorded when she was around fifteen years old. When RCA Records discovered the single, they advised fans not to purchase it. Months later, Warlock Records was set to release Just Be Free, an album which contains the demo tracks. Aguilera filed a breach of contract and unfair competition suit against Warlock and the album's producers to block the release. Instead, the two parties came to a settlement to release the album. Aguilera lent out her name, likeness and image for an unspecified amount of damages. Many of the details of the lawsuit remain confidential. When the album was released in August 2001, it had a photograph of Aguilera when she was fifteen years old.
Although Aguilera's debut album was commercially successful, she was dissatisfied with the music and image her management had created for her. Aguilera was marketed as a bubblegum pop singer because of the genre's upward financial trend. She mentioned plans of her next album to have much more depth, both musically and lyrically. Aguilera's views of Steve Kurtz's influence in matters of the singer's creative direction, the role of being her exclusive personal manager and overscheduling had in part caused her to seek legal means of terminating their management contract. In October 2000, Aguilera filed a breach of fiduciary duty lawsuit against her manager Kurtz for improper, undue and inappropriate influence over her professional activities, as well as fraud. According to legal documents, Kurtz did not protect her rights and interests. Instead, he took action that was for his own interest, at the cost of hers. The lawsuit came about when Aguilera discovered Kurtz used more of her commissionable income than he was allotted, and had paid other managers to assist him. She also petitioned the California State Labor Commission to nullify the contract. She revealed while recording her then upcoming album, "I was being overworked. You find out that someone you thought was a friend is stealing money behind your back, and it's heartbreaking. I put faith in the people around me, and unfortunately, it bit me in the butt." Kurtz was terminated as her manager. After terminating Kurtz's services, Irving Azoff was hired as her new manager. Kurtz countersued later that month for breach of contract, claiming that the singer violated the same agreement she had sued to void. In the lawsuit, he included others close to Aguilera, alleging their intent to sabotage his business relationship with her. He also singled out Azoff for being in violation of the terms of Kurtz's contract.
