Hayden Panettiere, who began her career as a child actress before starring in 'Heroes' and 'Nashville,' is dead at the age of 36. An acquaintance of the actress reportedly called 911; authorities arrived on the scene in Greenville, South Carolina (where she was living) to administer CPR after a suspected overdose and cardiac arrest. Hayden long lived with alcohol and opioid addiction; authorities say, there were no signs of foul play. To celebrate a life cut short, ET opens the vault, revisiting the memorable moments with Hayden over the years: from her first interview in 1998 at the premiere of 'A Bug's Life,' up until 13 weeks ago, when Hayden sat down to discuss her memoir, in which she revealed her struggles with postpartum depression, as well as the painful headlines that followed after she signed over custody of her daughter, Kaya, to live in Ukraine with her father, former boxer Wladimir Klitschko.
