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 Corazónes, starring Paola Núñez, Eugenio Siller and Juan Soler. Since 2016, she has been playing the character of Hilda Santana in Sin senos sí hay paraíso.

She has been married to Argentine-Colombian producer, actor and director Miguel Varoni since 1999 but they have been together since 1996. They acted together in a series called “Te voy a ensenar a querer”, “La Casa de Al Lado”. They met each other during Las Juanas, in which telenovela they both had parts.^[1]
