“Check on It” was Beyoncé’s first Billboard Hot 100 number-one solo single after Destiny’s Child.
The song was released in 2005 as a single from the soundtrack album for The Pink Panther, in which Beyoncé played the character Xania. It features Slim Thug and was produced by Beyoncé, Swizz Beatz, Sean Garrett, and others.
“Check on It” topped the Billboard Hot 100 for five weeks in early 2006. It was later included on the international editions of Beyoncé’s second solo studio album, B’Day.
The song is often overlooked because later singles such as “Irreplaceable” and “Single Ladies (Put a Ring on It)” became especially associated with Beyoncé’s solo stardom. However, “Crazy in Love” was her first solo number-one hit overall, while “Check on It” was the first after Destiny’s Child’s final period as an active group.
