Wrestling legend Dusty Rhodes died Thursday morning, the WWE confirmed on Twitter. He was 69.

The pro wrestler, whose real name was Virgil Runnels was famously known as “The American Dream.” The cause of death is unknown.

The wrestler was known for his polka dot tights and was inducted into the WWE Hall of Fame in 2007.

“Runnels became a hero to fans around the world thanks to his work ethic, his impassioned interviews and his indomitable spirit. Moreover, Runnels was a dedicated father to WWE Superstars Goldust (Dustin Runnels) and Stardust (Cody Runnels), a caring husband and a creative visionary who helped shape the landscape of WWE long after his in-ring career had ended,” the WWE said in a statement.

Rhodes is survived by his two sons, who also became wrestlers.

WWE executive Triple H wrote on Twitter of Rhodes’ death: “Saddened to hear the passing of Dusty Rhodes. Legend, teacher, mentor, friend…Love you Dream.”
