In 1994, she became the first Puerto Rican female to land a commercial deal with Pepe Jeans London and also for Diet Pepsi. During that year, Monge released Fiebre de Luna, along with a change of image. The hit album included compositions from Las Diego and produced the hit singles "A Pesar del Tiempo" and "Como Puedes". She teamed with singer Ricardo Montaner to do a concert and they earned a Guinness World Records as becoming the first singers to perform 3 concerts in 3 different cities (Mayagüez, Ponce and San Juan) – all in the same day. This could be done, using air transportation by helicopter. It was called: "El Suceso" (The Event).
