"You Know What You Did" was produced by Tony DiSanto, Adam DiVello, Liz Gateley, Sara Mast, Andrew Perry, Jason Sands, Robyn Schnieders, Sean Travis, Michael "Spike" Van Briesen, and Rick Van Meter. Rumors of a sex tape involving Conrad and Wahler, in addition to stories alleging that she invaded his house to retrieve it, surfaced in April 2007. Conrad adamantly denied both reports, commenting that "if I ever tried to get something back from Jason, it was probably just photo albums and stuff" and the producers "videotape my life five days out of the week. I don't need additional footage, you know?"
