Paying their respects. Cate Blanchett and Justin Theroux were seen visiting Mimi O'Donnell separately at her New York City apartment on Monday, Feb. 3, following the death of her longtime partner and their friend, Philip Seymour Hoffman.
The 46-year-old Oscar-winning actor was found dead in his West Village apartment from an apparent drug overdose on Sunday, Feb. 2. He is survived by O'Donnell and their three children: Cooper, 10, Tallulah, 7, and Willa, 5.
A source tells Us Weekly that Theroux, a good friend of the late star, was first spotted arriving at the West Village apartment building to visit Hoffman's family. Jennifer Aniston's fiance covered his face from photographers behind a black scarf, dark shades and a baseball cap.
"Justin is totally broken up about losing Phil," an insider tells Us. "He's doing his best to provide some comfort to Mimi and the kids. He can't believe this happened."
Blanchett, looking somber and wearing a black winter coat, trekked through piles of snow before reaching the apartment building. The Blue Jasmine actress carried a boxed telescope and a bag of what appeared to be toys for Hoffman's children. Blanchett starred alongside Hoffman in the 1999 thriller The Talented Mr. Ripley.
Hoffman's cause of death has not yet been determined, and an autopsy was said to be conducted Monday. Police told ABC News that roughly 65 bags of heroin were discovered inside the actor's apartment. After relapsing from 23 years of sobriety, Hoffman completed a 10-day rehab stint in May 2013.
The Wall Street Journal reports that Hoffman and costume designer O'Donnell were estranged at the time of his death. A source told Us that Hoffman's friends and family began to worry when he failed to get his kids from O'Donnell on Sunday.
The late actor's family released an official statement on his death Sunday: "We are devastated by the loss of our beloved Phil and appreciate the outpouring of love and support we have received from everyone. This is a tragic and sudden loss and we ask that you respect our privacy during this time of grieving. Please keep Phil in your thoughts and prayers."
