This soap opera was successful and that Cernadas travelled across Argentina, and many other countries, to relive his character at various acting venues for the next two years.
The soap opera, which featured romantic, family and mafia twists, became the number one show in many countries, such as the Dominican Republic, Chile, and Panama.
By 2004, Univision began to show Bésame Tonto in the United States; and Cernadas became the first Argentine actor to star in a Philippine telenovela, when he went to Manila to participate and team-up with Iza Calzado in Te Amo, Maging Sino Ka Man ("I Love You, Whoever You Are").
In 2015, while serving as councilor, he was appointed as head of the ANSES for Tigre, generating strong controversy due to his lack of experience.
