Ricky Martin -- an international superstar and native of Puerto Rico who has sold more than 15 million records worldwide appears to be conquering the US as well, thanks in large part to an electrifying performance of his worldwide smash hit (and 1998 World Cup theme song), "La Copa de la Vida," at the Grammy Awards show in February 1999. Martin is being hailed as the forerunner in a vanguard of Latin pop guards - a 'Latin fever' that is spreading worldwide. His 1998 Spanish-language album, Vuelve, won the 1999 Grammy for Best Latin Pop Performance and Martin's debut single ("Livin' La Vida Loca") from his first English-language album has become the biggest selling No.1 single in the history of Columbia Records.
