Cristian Castro  Christian Sáinz Valdés Castro (born in Mexico City 8 December 1974), known professionally as Cristian Castro or Cristian, is a Mexican pop singer and actor. He is the son of actors Veronica Castro and Manuel "El Loco" Valdés , and nephew of actors Ramón Valdés (known for playing Don Ramón in El Chavo del 8 ) and Germán «Tin-Tan» Valdés . Of artistic family heritage, he is also a nephew on his mother's side of José Alberto «El Güero» Castro, well-known producer of soap operas on Televisa . Known for his light tenor vocal range, Castro is regarded as one of the most skilled Hispanic pop singers of the last three decades. Juan Gabriel described Castro as "the man with the most faculties to sing in Mexico". Born in Mexico City, he is the son of actress and singer Verónica Castro and comedian Manuel "El Loco" Valdes. Castro also has a younger brother named Michelle Sáinz Castro. His uncle is José Alberto Castro, and his aunt is Beatriz Castro; both are producers. As a baby, he made his acting debut with her during the telenovela named "El Derecho de Nacer". Soon after, he appeared on a television commercial with her and on the Mexican version of the Broadway show "Mame" with actress Silvia Pinal. Castro is one of the best selling Latin artists and has worked with Latin producers Kike Santander, Rudy Pérez, and Richard Daniel Roman. In 1984, Castro made his first appearance on TV as a singer in the Televisa's child contest "Juguemos a Cantar", but he did not qualify for the finals because of his young age. Castro began his professional singing career in 1992 with the release of "Agua Nueva" at the age of 18. After appearing in several telenovelas and recording some albums as a teenager, he began his "internationalization" in 1993, starting with concerts in Puerto Rico. Castro dedicated a song to that country in his second album, "Un Segundo En El Tiempo", titled "Puerto Rico" as a way of thanking the Puerto Rican public for supporting his career. He modified his singing from the deep voice he employed in "Agua Nueva" to a softer one. His song "Nunca Voy a Olvidarte" ("I Will Never Forget You") became his first number-one hit on the Hot Latin Tracks chart in 1993 and helped start his career.
