Mexican singer Cristian Castro received his high school diploma on August 12, 2026, fulfilling a promise he made to his mother, Verónica Castro, on national television in 1996. The ceremony took place at the Teatro Royal Pedregal in Mexico City, with his mother present to witness the moment . Castro completed his studies through PrepaW, a distance-learning institution, in about two and a half years . The promise originated during an episode of the late-night show La Tocada, hosted by Verónica Castro, where she pressed her son about his unfinished education. Castro, then 21, declared, "Sí, que lo oigan bien, porque lo voy a hacer" . During that interview, he also recalled being bullied at school for his early fame from the song "Gallito Feliz," which contributed to his leaving school . PrepaW named him Graduado de Honor of its first generation, and the ceremony was streamed live on Instagram . Verónica Castro attended despite health issues, arriving with an oxygen tank, which added emotional weight to the event . This graduation marks a significant personal achievement for Castro, closing a chapter that began three decades ago.
