"Check on It" is an R&B song written by Beyoncé Knowles, Kasseem Dean, Sean Garrett, Angela Beyincé and Stayve Thomas for the soundtrack of the 2006 film The Pink Panther, in which Beyoncé co-stars. Although not included on its soundtrack album because it only contains the films scores, the song is included on Destiny's Child's greatest hits album #1's and on selected non-U.S. versions of Beyoncé's second solo studio album, B'Day. It was produced by Knowles and Swizz Beatz.
