"Whatcha Think About That" was written by its sole producer Polow da Don, Ester Dean, Missy Elliott, and Mickaël Furnon of the French rock group Mickey 3D.

The artist's vocals were recorded at Zac Studio in Atlanta, Georgia and The Boiler Room Studio in Santa Monica, California by Mike “Angry” Eleoploulos, Tal Herzberg, Tony Terrebonne, Aubry "Big Juice" Delaine, and Matt Wheeler, with the assistance of Johnathan Merritt and Bryan Morton.

[2] According to lead singer, Nicole Scherzinger, Elliott's contribution to the song elevated the group to another level, acknowledging they always wanted to work with her.

[6] The song impacted US contemporary hit radio stations on September 9, 2008, as the second single in the United States from Doll Domination,[7] and a remixes version was made available for digital download in the country on October 21, 2008.

[11][12] Built around a bhangra-inspired guitar riff, the Pussycat Dolls adopt a "spunky attitude" and lay "down the law to a deadbeat boyfriend" who is overbearing and controlling.

[18] "Whatcha Think About That" features three verses from Elliott, who joins the Pussycat Dolls "for a boy-baiting session",[11][19] and uses risqué lyrics in her "brash" rap teasing, "You ain't gonna get no more pussy...

"[12] Alex Fletcher from Digital Spy called "Whatcha Think About That" a "vibrant slice" of a song that finds the group "somewhere near the top of their game".

[20] The Sunday Times reviewer Elan Priya considered the former an exception to how Doll Domination "lacks any distinct personality" and highlighted Elliot's rap as "cheeky".

[21] Allison Stewart of The Washington Post wondered if it is the least objectionable song the Pussycat Dolls has recorded and described the track as a "nifty tale of sexual role reversal".

[19] Nic Oliver of musicOMH equated Elliott's contribution to someone who is sleepwalking, adding that the lyrics were written by a "sophomore student on a weekend bender".

[23] Nick Levine of Digital Spy wrote the song "is slightly disappointing after the hyperactive pop brilliance of 'When I Grow Up'".

[32][33] The two-day shoot was exhausting for the group as they kept on dancing until the early morning and in return some of the members, like Wyatt, began to blister in their feet.

[32] The music video is an ode to the group's burlesque origins, where they would frequently perform at Johnny Depp's Viper Room.
