And it's none other than his ex wife Kris Jenner!

We knew that Philip Seymour Hoffman had a drug problem.
"He was what we call a heavy 'red liner.' That means he liked to shoot [heroin] with a needle, but he also sniffed it daily. And he was majorly hooked on Oxy, too."
Oxycontin too? So horrible.
As for what tragically took his life, we'll have to wait for toxicology reports to be sure. But law enforcement sources say they found at least TEN bags of heroin in the NYC apartment where he died, two of which were already empty.
Just so heartbreaking to hear.
