"Dirty Little Secret" is a song by American rock band the All-American Rejects from their second studio album Move Along.

"Dirty Little Secret" was written by Nick Wheeler and Tyson Ritter, who claimed that because they were both at the time in long-term relationships with their girlfriends they had to "concoct some histrionics".

It's fluffy punk pop for middle class American teenage girls who don't want to listen to Ciara and 50 Cent, and would rather get sweaty with boys in eyeliner than shake their booty to the latest Missy Elliott remix.

"[8] "Dirty Little Secret" first charted in the United States on July 30, 2005, and became the band's first top 10 track on the Billboard Hot 100; peaking at number nine in January 2006.

It was filmed in May 2005 in Dorney Park & Wildwater Kingdom in Dorneyville, Pennsylvania and various other Allentown locations and was released a month later in mid-June.

It features a montage of various people holding up postcards sharing "dirty little secrets" while the band performs the song in an abandoned warehouse with the cards enlarged and displayed behind them in a backdrop.

The All-American Rejects agreed with Siega's idea and paid the website to use some of their postcards for the video, with the money going towards The Kristin Brooks Hope Center, a non-profit organization that funds a suicide hotline.
