Juan Gabriel, one of the most successful and beloved singers from Mexico, died at the age of 66 in Santa Monica, California, on Sunday morning. It's being reported that Juanga, as he was referred to by fans, died of an apparent heart attack.  

Police were called to a home in Santa Monica, and the singer was pronounced dead on arrival. No foul play is suspected.

His body is currently at the Los Angeles county medical examiner.

The charismatic crooner was currently in the middle of a nationwide tour in the United States. 

Juan Gabriel had just performed at the Los Angeles Forum on Friday night.

On Sunday, he was scheduled to perform a show in El Paso, Texas. His tour included 15 other shows that were scheduled through December. 

Tributes and messages poured in on social media as soon as Juanga's death was announced.

Juan Gabriel's career spans at least four decades and he's sold more than 100 million records. He's also been in five films including his debut in the 1975 Mexican film, "Nobleza Ranchera."

On January 7, we celebrated the birth of Juan Gabriel, with a look at his most cherished songs throughout his career. Alberto Aguilera Valadez was his birth name, and Juanga created his stage persona that would often be compared to the Elton John of Mexico.

"He has gone to become part of eternity and leaves us his legacy through Juan Gabriel, a character he created with the music he sang and performed across this world," his family said in a statement.

"Juan Gabriel hasn't died, as Alberto would say, 'As long as someone exists who sings my songs, Juan Gabriel will live.'"

His son also released a statement saying: "The untimely death of my father is a tragic loss for all of us, his family, his peers, and fans alike."

Fans gathered at his star on the Hollywood Walk of Fame to mourn the loss of the talented and multi-award winning singer.

Juan Gabriel wasn't ready to retire. Not by a long shot. Years after his first album, which was released in 1971, Billboard reports that he had the highest-grossing Latin tour of 2015, raking in $31.8 million for 32 shows in the U.S. and Puerto Rico alone. 

"It's really just shocking that he's gone."

"I compare him to Michael Jackson," Miranda Gastrom said of most treasured singer of Latinos, "because he's a legend, too, for Mexico."
