Problem: Beyoncé:

The remaining band members recorded "Independent Women Part I", which appeared on the soundtrack to the 2000 film, Charlie's Angels. It became their best-charting single, topping the U.S. Billboard Hot 100 chart for eleven consecutive weeks. In early 2001, while Destiny's Child was completing their third album, Beyoncé landed a major role in the MTV made-for-television film, Carmen: A Hip Hopera, starring alongside American actor Mekhi Phifer. Set in Philadelphia, the film is a modern interpretation of the 19th century opera Carmen by French composer Georges Bizet. When the third album Survivor was released in May 2001, Luckett and Roberson filed a lawsuit claiming that the songs were aimed at them. The album debuted at number one on the U.S. Billboard 200, with first-week sales of 663,000 copies sold. The album spawned other number-one hits, "Bootylicious" and the title track, "Survivor", the latter of which earned the group a Grammy Award for Best R&B Performance by a Duo or Group with Vocals. After releasing their holiday album 8 Days of Christmas in October 2001, the group announced a hiatus to further pursue solo careers.
