Life and Career
Vietto was born in Côte d'Ivoire to Mario Alejandro Vietto and María Pía, but moved to La Rioja, Argentina at age one and a half. When he was 15, he relocated to Cordoba to play soccer for the lower levels of the Instituto de Córdoba, working his way up to a starter position. He played until he was 17 and then moved to Buenos Aires to audition for the Argentine remake/spin-off of High School Musical. The audition process was documented in the reality competition show High School Musical: la Selección. Vietto was a semifinalist and won a role equivalent to Chad or Zeke in High School Musical: El desafío.
In 2011, Vietto was cast as Mateo on the Disney XD LA show Peter Punk. As Mateo, Vietto was a guitarist in the Rock Bones band which also made guest appearances on Violetta. After the show ended, Vietto formed the Primantes band with his former co-stars and Tom Huergo.
While auditioning for the Disney XD LA show Once, Vietto received a call asking him to attend a casting for a role in Soy Luna instead. He landed the role of Pedro and was on the show from 2016 to its end in 2018. He also wrote a song for the show called "Decirte lo que siento," and went on three tours across Latin America and Europe with the show.
