Catherine Siachoque

María Alexandra "Catherine Siachoque" Gaete (born January 21, 1972) is a Colombian actress best known for her (mostly villainess) roles in numerous telenovelas.

Siachoque was born in Bogotá, Colombia to Felix Siachoque and Blanca Gaete.

Siachoque has appeared in Telemundo produced series such as Pecados Ajenos, Tierra de Pasiones, Te Voy a Enseñar a Querer, La Venganza, Amantes del Desierto, and the TV anthology series Decisiones. Though she has become type cast as villainess, some would consider her a sympathetic character as Doña Hilda de Santana in Telemundo telenovela Sin Senos no hay Paraíso, aside from the fact that she possibly committed incest in having carnal relations with her daughter's boyfriend. In 2010, she reverted to villainess as Cecilia Altamira in the Telemundo remake of ¿Dónde Está Elisa?. In 2011, she later played a complex character in another telenovela remake produced by Telemundo, La Casa de al Lado wherein she was the mistress (amante) of a character portrayed by her real-life husband Miguel Varoni, wherein she interacted with Maritza Rodríguez, Gabriel Porras, and Karla Monroig. In 2014, she marked her villainess return in Reina de Corazones, starring Paola Núñez, Eugenio Siller and Juan Soler.

She has been married to Argentine-Colombian actor and director Miguel Varoni since 1997.
