Top-selling music star Juan Gabriel has been hospitalized in Las Vegas with pneumonia,causing him to postpone three California shows this week that were part of his "Volver" tour.

The 64-year-old "Divo de Juarez" was rushed to intensive care Monday, according to a statement released Tuesday. Gabriel had performed an extended, three-hour concert the night before at the Mandalay Bay resort in Las Vegas.

The Mexican singer is one of the best-selling Latin recording artists of all time, with more than 100 million albums sold. He was named Person of the Year in 2009 by the Latin Recording Academy, which produces the Latin Grammys.

Gabriel's "Volver" tour began earlier this month and includes stops in Houston, New York City and Miami. The show features the singer's mariachi band and a full orchestra on a 360-degree stage.
