Mexican President Enrique Pena Nieto took to Twitter.com to pay tribute to one of the country's most beloved stars, writing, "I regret the death of Juan Gabriel, one of the great musical icons of our country. My condolences to your family and friends. A voice and a talent representing Mexico. His music, a legacy to the world. He was gone too soon. Rest in peace."
