Nikki Died twice. I'm a big Crue fan (or really big Rock N Roll fan) I read both The Dirt and Nikki Sixx's The Heroin Dairies. Nikki Died of an OD once on the Theater of Pain tour on Valentines Day somewhere over in the UK. Then Nikki died of an OD again in LA on the Girls tour while partying with Slash, Steven Adler, (both of Guns N Roses) Robin Crosby (Ratt) and Slash's Girlfriend. Slash's Girlfriend kept doing CPR till the paramedics arrived and were able to revive Nikki.
