Michael Jackson fans all over the world are paying tribute to the King of Pop on the 10th Anniversary of his death. Fans in Madrid, Spain paid tribute to Michael with a flashmob at Principe Pio Station on Tuesday, June 25.

Jackson died from a prescription drug overdose at his Southern California mansion on June 25, 2009. He was 50.

Former Dr. Conrad Murray was eventually convicted for his role in dispensing the anesthetic Propofol that caused Jackson’s death.

Radar Online reports Jackson’s death has taken a toll on his three children and his siblings.

“He would be absolutely heartbroken and devastated to see what has become of them,” the source told Radar. “His children, as well as his entire family, were the most important things in his life.”

The source added: “They were, in fact, his only real human connection. In a world that Michael didn’t trust, and often times feared, his family were his lifeline. They kept him going.”

Jackson’s fans heeded a call from representatives of Jackson’s estate to pay tribute to the late star on the 10th anniversary of his death.

A statement issued by his estate to the Associated Press (AP) marking the 10th anniversary of his passing called him a “gifted artist” and “extraordinary humanitarian” and urged fans to honor his memory by engaging in charitable acts.

“United in grief, the world wept not only at the loss of an artistic genius but at the void left by the loss of a father, son and brother,” the statement continued. “A decade later, Michael Jackson is still with us, his influence embedded in dance, fashion, art and music of the moment. He is more important than ever. But the true measure of Michael was his giving to others which came in many forms.”

The estate asked fans to mark his passing by, “planting a tree, volunteering at a shelter, cleaning up a public space or helping someone who is lost find their way.”

Fans gathered at the opulent mansion in the Holmby Hills neighborhood of Los Angeles, where Jackson received the fatal dose of Propofol before being declared dead at a nearby hospital.

Fans will also attend a vigil at Forest Lawn Memorial Park in Glendale, California, where the singer was laid to rest, and others plan to visit Jackson’s star on the Hollywood Walk of Fame, WENN.com reports.

Thousands of fans remembered Jackson on social media, including his nephew Taj, who thanked well-wishers for focusing on the pop star’s legacy rather than the controversy surrounding the recent documentary Leaving Neverland, in which two former Jackson associates claimed the singer molested them as children.

“I’m so happy to read people’s positive tweets about my uncle,” Taj wrote on Twitter. “This has really helped me with my grieving. It also feels good to know that most people are seeing thru all the fake bs (bulls**t).”
