The multiple Grammy Award winner will be part of the search for the ultimate Latino boy band when the new show debuts later this year (15).
Sanz will judge the singing contest alongside Italian pop star Laura Pausini and Martin, who will also serve as an executive producer with reality TV veteran Simon Cowell.
In a recent press conference for his new album, Sirope, Sanz shared his excitement for his new project, saying, "We're going to find those five guys who will revolutionise music in this country and all over Latin America. I'm already excited."
This isn't the first time Sanz will help guide aspiring artists - both he and Pausini had mentoring stints on La Voz (The Voice) in Mexico.
