12 Corazones is a Spanish-language dating game show produced in the United States for the television network Telemundo from 2005 to 2017, based on its namesake Argentine TV show format. The show was filmed in Los Angeles and revolved around the twelve Zodiac signs that identify each contestant. The show was hosted by Penélope Menchaca and featured advice from co-host Maximiliano Palacio, an Argentine former soccer player turned actor, and Edward'O, an astrologist; Palacio and Edward'O appeared alternately in some episodes and simultaneously in others.
In August 2009, Telemundo added English subtitles as closed captions on CC3, airing on Universo in that format.
