Mimi O’Donnell, Philip Seymour Hoffman’s longtime girlfriend, reportedly screamed after hearing of the actor’s death on Sunday.
Hoffman, 46, was found dead in his Manhattan apartment on February 2, possibly of a drug overdose.
Hoffman and O’Donnell have been together since 1999.
They have a son, Cooper Alexander, who was born in March 2003.
Their two daughters, Tallulah and Willa, were born in November 2006 and October 2008.
A source told ShowBizSpy that Mimi is heartbroken over the loss.
“Mimi is inconsolable,” the source said. “He had his problems, but she thought he was on the road to recovery following his recent rehab stint.
“Mimi already had a tough few days, after the recent hoax that claimed Philip had died.”

Hoffman was clean for 23 years but told TMZ in 2013 that he went into rehab for 10 days after beginning to use prescription pills again, and using heroin for a week.
A needle was reportedly sticking out of his arm when his body was found on Sunday. Police found eight small bags, six of which were empty and two of which contained heroin, according to TMZ.
Two law enforcement officials who spoke on condition of anonymity said that Hoffman died from a drug overdose and confirmed that envelopes that appeared to contain heroin were found with him.
Hoffman was supposed to pick up his children at 9 a.m. but didn’t show up, which prompted friend and collaborator David Katz to check in on him.
Hoffman’s family said in a statement that “We are devastated by the loss of our beloved Phil and appreciate the outpouring of love and support.”
“This is a tragic and sudden loss and we ask that you respect our privacy during this time of grieving,” they added.

Hoffman was renowned as a character actor. He won the Oscar for best actor in 2006 for portraying writer Truman Capote in “Capote.”
He was also nominated for the 2013 Academy Award for best supporting actor for portraying the charismatic leader of a religious movement in “The Master.”
Other memorable roles included Brandt, Jeffrey Lebowski’s personal assistant in “The Big Lebowski,” and Paul Zara, the senior campaign manager for Governor Mike Morris in “Ides of March.”

Tributes poured in from Hollywood figures.
“Damn, We Lost Another Great Artist,” Spike Lee, who directed him in “25th Hour,” said on Twitter.
Kevin Costner said in an interview: “Philip was a very important actor and really takes his place among the real great actors. It’s a shame. Who knows what he would have been able to do? But we’re left with the legacy of the work he’s done and it all speaks for itself.”
Lionsgate, which distributes the adaptations of Suzanne Collins’ multimillion-selling novels, called his death a tragedy and praised him as a “singular talent.” The last two “Hunger Games” movies are scheduled for release in November 2014 and November 2015.
Besides his film work, Hoffman was in multiple plays over the years.
On Broadway, he took on ambitious parts like Willy Loman in “Death of a Salesman,” Jamie in “Long Day’s Journey Into Night” (his parents were played by Brian Dennehy and Vanessa Redgrave) and both leads in “True West.” All three performances were Tony nominated.
His 2012 work in “Death of a Salesman” was praised as “heartbreaking” by theater critic Mark Kennedy.
“Hoffman is only 44, but he nevertheless sags in his brokenness like a man closer to retirement age, lugging about his sample cases filled with his self-denial and disillusionment,” Kennedy wrote. “His fraying connection to reality is pronounced in this production, with Hoffman quick to anger and a hard edge emerging from his babbling.”
