It was released as the album's fourth single on July 31, 2006 to urban contemporary stations in the United States.

Quentin B. Huff of PopMatters complimented Scherzinger's vocals and highlighted as a standout from the album but Johnny Dee of The Guardian was more critical.

[1] In 2006, American singers Avant and Nicole Scherzinger re-recorded the song for the former's fourth studio album, Director.

[2] Scherzinger, who at that time found success as the lead singer of the Pussycat Dolls and was preparing to launch her solo career, wanted to include the song on her shelved album, Her Name is Nicole, however, Avant's team insisted that it should go on his record.

[3] "Lie About Us" marks their second collaboration together as Avant previously appeared on an urban remix of the Pussycat Dolls' song "Stickwitu" released in September 2005.

[11] The song is about secret relationship of a man and his mistress with the promise to leave the other woman and come clean to the world about their affair as chronicled in the lines, "Please don't say you wanna give up / How do I tell her that I'm fallin' in love / And I know you're waiting patiently for that day that we no longer have to lie about us".
