Robbie Williams was heading towards a "Heath Ledger kind of scenario" because of his past drug addiction.
The 39-year-old singer was "days away from dying" on several occasions and has compared himself to the late actor who died from an accidental overdose in 2008.
Speaking to the Daily Mail Weekend magazine, he said: "I managed to escape by the skin of my teeth and I'm lucky. I was days away fro dying quite a few times on all manners of substances. There could easily have been a Heath Ledger kind of scenario.
"Unfortunately I've been in a place where I didn't care if I was on the planet or not. I do care now, but at the time I was so deep into addiction I knew I was probably going to die soon but I didn't care.
"I was taking a whole cocktail of drugs. My left arm went numb I was taking so much cocaine."
