Mimi O'Donnell and actor Philip Seymour Hoffman attend the premiere of "The Ides of March" at the Ziegfeld Theater on October 5, 2011 in New York City.
Actor Philip Seymour Hoffman left a will that bequeathed all of his personal property to the mother of his three children.
His will was made public Wednesday.
It names Marianne "Mimi" O'Donnell as the sole beneficiary and identifies her as his "friend and companion."
The 46-year-old Oscar-winning actor died Feb. 2 at his West Village home of an apparent heroin overdose.
More tests are needed to determine what exactly killed Hoffman, who was found with a syringe in his arm and what authorities said were dozens of packets of heroin in his apartment.
Hoffman spoke candidly over the years about past struggles with drug addiction. After 23 years sober, the versatile actor reportedly checked himself into rehab for 10 days last year after relapsing in 2012.
