In February 2001, Spears signed a $7-8 million promotional deal with Pepsi, and released another book co-written with her mother, titled A Mother's Gift. Her self-titled third studio album, Britney, was released in November 2001. While on tour, she felt inspired by hip hop artists such as Jay-Z and The Neptunes and wanted to create a record with a funkier sound. The album debuted at number one in the Billboard 200 and reached top five positions in Australia, the United Kingdom and mainland Europe and sold over 12 million copies worldwide. Stephen Thomas Erlewine of AllMusic called Britney "the record where she strives to deepen her persona, making it more adult while still recognizably Britney. [...] It does sound like the work of a star who has now found and refined her voice, resulting in her best record yet." The album was honored with two Grammy nominations--Best Pop Vocal Album and Best Female Pop Vocal Performance for "Overprotected"-- and was listed in 2008 as one of Entertainment Weekly's "100 Best Albums from the Past 25 Years". The album's first single, "I'm a Slave 4 U", became a top-ten hit worldwide.  Spears's performance of the single at the 2001 MTV Video Music Awards featured a caged tiger and a large albino python draped over her shoulders. It was harshly received by animal rights organization PETA, who claimed the animals were mistreated and scrapped plans for an anti-fur billboard that was to feature Spears. To support the album, Spears embarked on the Dream Within a Dream Tour. The show was critically praised for its technical innovations, the piece de resistance being a water screen that pumped two tons of water into the stage. The tour grossed $43.7 million, becoming the second highest grossing tour of 2002 by a female artist, behind Cher's Farewell Tour. Her career success was highlighted by Forbes in 2002, as Spears was ranked the world's most powerful celebrity. Spears also landed her first starring role in Crossroads, released in February 2002. Although the film was largely panned, critics praised Spears's acting and the film was a box office success. Crossroads, which had a $12 million budget, went on to gross over $61.1 million worldwide.  In June 2002, Spears opened her first restaurant, Nyla, in New York City, but terminated her relationship in November, citing mismanagement and "management's failure to keep her fully apprised". In July 2002, Spears announced she would take a six-month break from her career; however, she went back into the studio in November to record her new album. Spears's relationship with Justin Timberlake ended after three years. In December 2002, Timberlake released the song "Cry Me a River" as the second single from his solo debut album. The music video featured a Spears look-alike and fueled the rumors that she had been unfaithful to him. As a response, Spears wrote the ballad "Everytime" with her backing vocalist and friend Annet Artani. The same year, Limp Bizkit frontman Fred Durst said that he was in a relationship with Spears. However, Spears denied Durst's claims. In a 2009 interview, he explained that "I just guess at the time it was taboo for a guy like me to be associated with a gal like her."Answer this question using a quote from the following article:
