Check on It

"Check on It" is a song recorded by American singer Beyoncé. It was written by her, Swizz Beatz, Sean Garrett, Angela Beyincé and Slim Thug, and produced by Swizz Beatz. The song was supposed to be featured on the soundtrack for the 2006 film The Pink Panther, in which Beyonce co-starred as Xania. As it was ultimately not included on the soundtrack, the version with additional vocals from Slim Thug was placed on the 2005 Destiny's Child's greatest hits album #1's. Columbia Records released a remix version of "Check on It" featuring both Slim Thug and Bun B as the second single from #1's on December 13, 2005.

"Check on It" is an R&B and hip hop song, which is instrumentally complete with a heavy bassline, strings, and wind instrument. The song consists of two verse-raps by Slim Thug. "Check on It" was mostly well received by music critics, who complimented the arrangement and the vocal deliveries.

"Check on It" was not originally intended as a single from #1's. However, it received some rotation on US radio stations, after the release of the first single "Stand Up for Love" (2005), which failed to chart on the Billboard Hot 100. Eventually, "Check on It" was released as a single; it debuted on the US Hot 100 in November 2005. The song peaked at number one for five consecutive weeks, becoming one of the two longest-running number-one singles of 2006, and Beyoncé's credited third US number-one single. Internationally, it reached number one in New Zealand and the top ten in Canada and several European countries.

The accompanying music video for "Check on It" was directed by Hype Williams, and premiered on December 16, 2005, on MTV. The version of the song used in the video features a remix of "The Pink Panther Theme". Incorporating 1950s influences, the video was shot in pink to brand the relationship with The Pink Panther. It won Best R&B Video at the 2006 MTV Video Music Awards, and was nominated for Video of the Year at the BET Awards 2006. During the time of it release, Beyoncé did not perform "Check on It" in any televised appearances, as it contains the second verse and chorus sung by and with Kelly Rowland. However, Beyonce did later include it in her set list on the tours The Beyoncé Experience (2007) and I Am... World Tour (2009–2010). She also included it in her Coachella performance (2018).
