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 October 11, 2005.

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.

However, it received heavy rotation from US radio stations after the release of the first single "Stand Up for Love" (2005), which recorded by all members of Destiny's Child was a commercial failure.

[7] Meanwhile, "Check on It" debuted on the US Billboard Hot 100 chart in November 2005, that is, before its official release as it had amassed considerable listener impressions.

The song was included as a bonus track on the deluxe edition of Beyoncé's second studio album, B'Day in European countries on April 3, 2007.

[6] "Check on It" is a midtempo R&B and hip hop song,[7] which makes use of a heavy bassline,[16] strings, wind instrument,[17] and frequent "swinging pelvic taunts".

[18] "Check on It" starts with a verse-rap from Slim Thug: "Good girls gotta get down with them gangstas / Go head girl put some back and some neck up on it..."[18] The rapper sounds like a 1975 Mercury Cougar turning over as he growls in his burly purr, as written by Bret McCabe of Baltimore City Paper.

[7][16] The chorus lines; "Dip it, pop it, twerk it, stop it, check on me tonight" are sung in a very quick and breathless manner by Beyoncé.

[18] Before the song ends, Beyoncé repeats the chorus lines four times as additional vocals of hers are played in the background.

[18] Music critics received the song positively, complimenting Beyoncé's vocal performance, and the easiness as well as the confidence she displays while singing her lyrics.

A reviewer from the UK website Contactmusic.com described "Check on It" as a "booty shaking anthem" and complimented Beyoncé for switching to a club song after "Stand Up for Love".

[16] Bret McCabe of Baltimore City Paper noted that the song is "less a DC joint than a Beyoncé sex-kitten solo".

[21] James Anthony of the British newspaper The Guardian wrote that the song "espouses a blissful disregard for traditional songwriting conventions.

No Hova (Jay-Z) this time, but Houston rapper Slim Thug's lazy southern drawl suits the fractionally slower tempo.

[31] According to Mediabase and Nielsen Broadcast Data Systems, "Check on It" passed the 200 million audience impressions mark in on January 31, 2006.

[32] Beyoncé thus became the second female singer to achieve this feat in the US after Mariah Carey's two singles "We Belong Together" and "Shake It Off" both passed the same mark within 2005.

[42] When demand was growing for the song, Beyoncé decided to make a music video for it, serving as promotion for both #1's and The Pink Panther.

"[43] In the video, Beyoncé is seen mostly in all pink, and the dancers wear PVC jackets and dance around rippling satin sheets.

Where black bars normally appear on a 4:3 (full screen) television showing a widescreen production, footage is displayed of curtains moving in the background.

As she sang, animated graphics of turntables, faders and other club equipment were projected behind Beyoncé, her dancers and musicians.
