Two days after Philip Seymour Hoffman was found dead of an apparent drug overdose, his long-time girlfriend Mimi O’Donnell, who was estranged from Hoffman at the time of his death, stepped out at an Upper East Side funeral home to begin preparations.

The 46-year-old costume designer was visibly distraught as she ducked inside the home alongside Hoffman’s personal assistant, Isabella Wing-Davey.

According to reports, a private wake for family and friends is planned at the Frank E. Campbell Funeral Home on Thursday from 5 pm to 9 pm. The funeral will take place the following day before noon at St. Ignatius of Loyola on Manhattan’s Upper East Side.

Before O’Donnell left for the funeral home, she received a few famous visitors at her Upper West Side apartment, including Joaquin Phoenix, legendary photographer Annie Leibovitz and actor Bobby Cannavale.

Yesterday, actors Cate Blanchett and Justin Theroux were seen visiting O’Donnell as well.

Hoffman’s mother, Marilyn O’Connor, also arrived today at the apartment the couple used to share when they were together.

O’Connor divorced from the “Capote” star’s father in 1976 and largely raised the actor on her own. She reportedly helped Hoffman through his first battle with heroin in 1989 and the Oscar winner gushed about his mom during his 2006 Best Actor acceptance speech.

“My mom’s name is Marilyn O’Connor and she’s here tonight. And I’d like if you see her tonight to congratulate her, because she brought up four kids alone and she deserves a congratulations for that,” he said. “We’re at the party, Ma, you know?”

He continued, “She took me to my first play and she stayed up with me and watched the NCAA Final Four and her passions became my passions. Be proud mom, because I’m proud of you. We’re here tonight and it’s so good.”
