Litzy Vanya Domínguez Balderas (better known as Litzy) is a Mexican actress and singer. She was born in Mexico City on October 27, 1982.

She is known for having been in the Mexican singing group Jeans, and for her ("always" protagonist) roles in Telenovelas: Televisa's DKDA Sueños de Juventude; Telemundo's Daniela, Amarte Asi, and Una Maid en Manhattan; Venevisión-with-Univisión's Pecadora; and Azteca [Mexico] TV's Quiéreme Tonto, retitled simply Quiéreme. Probably her most successful recent song is "La Rosa." She sang the entrada song (opening theme song) for both Daniela ("Sobreviveré") and Amarte Asi ("Amarte Asi"). For Una Maid en Manhattan, she sings the entrada as a duet with Siller. She also has recorded a theme song entitled "Pecadora" for Pecadora. However, as recently aired, the telenovela is not using that song for its entrada, but (in part) as the closing theme. Amarte Asi has also been aired with a different title, Frijolito. It is also notable that Litzy won a sort of acting-contest reality show run by Telemundo entitled Protagonistas de la Fama. Apparently her winning of that contest landed her the starring role in Amarte Así. She also was the star of Daniela, and recently starred in Pecadora, Quiéreme Tonto (2010), and Una Maid en Manhattan (2012).
