Though he trained as an architect, FernŠndez turned to singing in 1991. A year later, he released his first album. Since then, he has recorded 13 albums and sold a reported 20 million records, working with producers such as Emilio Estefan and Kike Santander. FernŠndez also has portrayed the lead role in Zapata, a 2003 movie about the Mexican revolutionary hero Emiliano Zapata by filmmaker Alfonso Arau.
Although he has many publicized female companions, it is rumored that he and Ricky Martin have been romantically involved; bisexual singer Miguel Bosť has also neither confirmed nor denied a 2004 tabloid report that he and FernŠndez have been involved as well. Although FernŠndez has been quoted as saying that he is not homosexual, a Chicago based Univision reporter reported that Fernandez visited a popular gay club, The Man-Hole, during his 1996 visit to perform at the UIC Pavilian in Chicago.
