• 2008–09: Marriage, I Am... Sasha Fierce, and films
In 2002, Knowles began dating Jay-Z, with whom she has collaborated several times. Rumors began to circulate about their relationship after Knowles was featured on "'03 Bonnie & Clyde". In spite of persistent rumors, they remained discreet about their relationship. On April 4, 2008, Knowles and Jay-Z got married in New York City. Knowles did not publicly debut her wedding ring until the Fashion Rocks concert on September 5, 2008, in New York City. Before they were married, Knowles and Jay-Z were named as a power couple in Time magazine's 100 Most Influential people of 2006.
In November 2008, Forbes magazine reported that Knowles earned $80 million between June 1, 2007 to June 1, 2008, for her music, tour, films and fashion business. This made her the world's second best-paid music personality for this span of time. Knowles released her third studio album I Am... Sasha Fierce, on November 14, 2008. The album introduced Knowles' alter-ego Sasha Fierce. It debuted at number one on the Billboard 200 and sold 482,000 copies in its first week. It became Knowles' third consecutive number-one album in the US as a solo artist. I Am... Sasha Fierce was certified double platinum by the RIAA. The album has sold over 2.9 million copies in the United States, and 7 million copies worldwide.
"If I Were a Boy" and "Single Ladies (Put a Ring on It)" were released as the album's first and second lead singles, respectively. The first lead single peaked at number three on the Billboard Hot 100 chart, while the second peaked at number one, and became Knowles' fifth number-one single. "Single Ladies" spent four non-consecutive weeks at the top spot. Its music video has achieved fame for its intricate choreography, which has been credited as having started the "first major dance craze of both the new millennium and the Internet". Knowles revealed that the inspiration for the video was a 1969 Bob Fosse routine entitled "Mexican Breakfast" seen on The Ed Sullivan Show, which featured Fosse's wife, Gwen Verdon, dancing with two other women. This prompted a legion of imitations and parodies from men and women all around the world, including celebrities Justin Timberlake Joe Jonas, Tom Hanks and US President Barack Obama. The music video received nine nominations at the 2009 MTV Video Music Awards and ultimately won the award for Video of the Year and an additional two awards, though its loss in the Best Female Video category to Taylor Swift's "You Belong with Me" led to a controversy during the ceremony.
