Charlie Balducci -- best known for his time on the MTV reality show, "True Life" -- died from a drug overdose ... TMZ has learned.
The New York City Medical Examiner's Office tells TMZ ... Charlie's cause of death is acute intoxication by the combined effects of oxycodone, hydrocodone and alprazolam. The manner of his death has been ruled accidental.
TMZ broke the story ... Balducci was found unresponsive in his bed back in July and paramedics pronounced him dead at the scene. When we spoke to his mom, she told us his death came unexpectedly since he hadn't exhibited any kind of sickness.
For the non-hardcore reality TV aficionados out there ... Balducci is known as a trailblazer of sorts in the reality TV world after appearing in "True Life: I'm Getting Married." He allowed MTV cameras to follow him for 4 months before marrying Sabrina ... which ultimately produced one of the most infamous rants ever caught on TV.
Quick recap ... the limo driver was running late on the day Balducci was supposed to get married, prompting him to threaten the limo driver, "I will gut you like the piece of s*** you are" and "I'll hunt you down like cattle."
