Career

Stéfano de Gregorio kicked off his career remarkably early, debuting at age six in the long-running children’s series Chiquititas around 2000-2001, where he played Cupido and quickly caught attention for his natural charm.

He followed with small roles in Rincón de Luz (2003) and landed a breakthrough part in Floricienta (2004-2005) as Tomás Fritzenwalden, a role that turned him into a household name among young audiences and solidified his status in Cris Morena‘s productions.

His film debut came even earlier with Valentín (2002), directed by Alejandro Agresti, where he portrayed Roberto Medina alongside a strong ensemble cast. These early experiences built his foundation in both screen and stage work, including theater adaptations of his TV shows.

Stéfano de Gregorio reached peak teen stardom with his co-starring role as León “Lleca” Benítez in Casi Ángeles (2007-2010), a massive hit that included live theater seasons, most notably the 2007 Gran Rex production, and earned him widespread recognition across Latin America.

He continued with guest spots and supporting roles in series like Peter Punk (2011) as Igor, Esperanza mía (2015) as Federico Minelli, and others, while balancing modeling opportunities and occasional reality appearances.

His ability to transition from child actor to young adult performer kept him relevant, though he explored other interests like sports and digital content during quieter acting periods.

Stéfano de Gregorio maintains visibility through reality formats, finishing third on The Challenge: Argentina: El Desafío (2023) and competing in dance shows like Bailando por un sueño and Dancing with the Stars Argentina.

He has also pursued esports, streaming, and social media influence, amassing nearly a million Instagram followers. His work reflects a shift toward multifaceted entertainment, blending acting legacy with modern digital and competitive pursuits, and he continues to draw fans nostalgic for his youth-era roles while building new audiences.
