One of del Castillo's first known romantic relations was with Emilio Azcarraga Jean son of media mogul Emilio Azcárraga Milmo, and now CEO of the largest mass media company in Latin America, the Televisa Group. On February 3, 2001, she married football player Luis García. The marriage was dissolved on September 1, 2004. In August 2009, del Castillo married Aarón Díaz in a Las Vegas ceremony. On July 26, 2011, it was announced that Kate and Díaz were separating. Del Castillo was briefly romantically connected with Sean Penn from 2015 to 2016, although the actor's representatives contest this. It has been frequently asserted in the media that del Castillo was romantically involved with Joaquin "El Chapo" Guzman, allegations that the actress vehemently denies.
