Ricky Martin has gone home. As the music sensation's private jet touched down at San Juan's Luis Muñoz Marin International Airport yesterday, dozens of fans greeted him, screaming, "We love you Ricky!" A helicopter then swooped him off to an undisclosed hideaway, where he is preparing for his first concerts in his homeland in two years, starting with three this weekend in San Juan. Martin, 28, also told reporters that he may visit Vieques, the Puerto Rican island where protesters have camped out on a U.S. Navy bombing range in order to halt military exercises. Martin, who has sided with the protest, discussed the issue with one of President Clinton's aides during a White House visit last week. Martin's manager, Angelo Medina, also said that Ricky is working on a new album with songwriter Robi Rosa, a fellow Menudo alum.
