Jay-Z was Beyoncé’s duet partner on the 2003 single “Crazy in Love.”
The song was released as the lead single from Beyoncé's debut solo album, Dangerously in Love. It combines a prominent horn sample from the Chi-Lites' “Are You My Woman (Tell Me So)” with a rap verse by Jay-Z.
“Crazy in Love” became Beyoncé's first number-one single as a solo artist in the United States. It also established a recurring musical partnership between the two artists, who later married and collaborated on further recordings.
The song is sometimes confused with “03 Bonnie & Clyde,” an earlier Beyoncé and Jay-Z collaboration released in 2002. That track was credited to Jay-Z featuring Beyoncé, while “Crazy in Love” was Beyoncé's solo single featuring Jay-Z.
