"Beep" had initially been set for release as the second single after "Don't Cha". However, the single was pushed back due to the fact that The Black Eyed Peas had just released their single "My Humps". Management felt both songs carried a somewhat similar message, and since "Beep" features vocals from Will.I.Am from The Black Eyed Peas, they felt best to delay the single ("Stickwitu" was released in its place). Although both songs had a similiar meaning, "Beep" actually received approval from critics, while "My Humps" was trashed. However, promotional vinyls were sent to clubs. "Beep" received very little play in the clubs, therefore never charting when it was originally released.
This is one of the first singles by The Pussycat Dolls that features two other dolls with solo parts. Melody Thornton and Carmit Bachar sing a verse of the bridge towards the end of the song (The only other song that has been released commercially that features each girl with a solo part is the bonus track "Santa Baby," featured on the "Stickwitu" CD single). Its main riff is sampled from Electric Light Orchestra's "Evil Woman" written by Jeff Lynne.
Co-writer Kara DioGuardi also co-wrote the track "Two Way," recorded by Nicole Kea's previous group Eden's Crush, plus the PCD tracks "I Don't Need a Man" and "Flirt."
The video starts with Nicole meeting Will.I.Am in an elevator. Will.I.Am explains his attraction to which Nicole replies by implying she doesn't care about him looking at her (I don't give a (BEEP) Keep lookin' at my (BEEP)) Nicole then enters the Dolls apartment, and, concluding the chorus, they begin a dance routine throughought the second verse. Will.I.Am then enters the room, but quickly exits as Carmit throws a bottle of water at him. The dolls are then seen at a club, dancing to a piece of music added in especially for a video dance routine, but not featured in the album/single release. The dolls are then seen in solo dance spots in front of a large set of speakers, sometimes with Will.I.Am, as the video comes to a close.
