The model's cause of death was previously listed as "deferred" after the completion of an autopsy

Kim Porter‘s cause of death has been released.

The model and ex-girlfriend of Sean “Diddy” Combs died of lobar pneumonia, the Los Angeles County Department of Medical Examiner-Coroner announced Friday. The manner of death has been certified as natural.

Porter had been suffering from flu-like symptoms for days at the time of her death. The coroner’s report, obtained by The Blast, says that Porter’s bedroom contained bottles of water, sports drinks and Pedialyte on a nightstand, as well as a bowl of what appeared to be tomato soup.

An autopsy was completed on Porter a day after she was found dead in her home on Nov. 15, but her death certificate previously stated her cause of death as “deferred” and the manner of death as “pending investigation.” She was 47.

“On Nov. 16, an autopsy was performed on Porter. The cause of death was deferred pending additional tests. Porter’s body has since been released from our facility,” a spokesperson for the Los Angeles County Medical Examiner-Coroner said in a statement released at the time.

Porter was buried in her hometown of Columbus, Georgia on Nov. 24. During the elaborate public funeral held at Cascade Hills Church, Combs, 49, arranged for Porter’s casket to travel in a carriage pulled by horses and acclaimed pastor T.D. Jakes officiated the service.

In an audio recording of Combs’ eulogy obtained by TMZ, Combs described his unique relationship with Porter and made a promise to their children: Christian, 20, twins D’Lila Star and Jessie James, 12 (his kids with Porter), Quincy, 27, (Porter’s son from her previous relationship with Al B. Sure! whom Combs helped raise) and Justin, 25, and Chance, 12 (Combs’ children with exes Misa Hylton-Brim and Sarah Chapman, respectively).

“I just want to say to my kids, Justin, Christian, D’Lila, Jessie, Chance and the other man in the house, Quincy: Your mother instilled in me this, and I pledge in front of everybody right now that I will always be there for you,” Combs said as the audience applauded. “I will always take care of you.”

Eliciting laughter and claps, Combs added, “To the girls especially, we about to enter some different type of times. I want you to be able to talk to me about everything, and I mean everything, and I mean everything.”

Shortly before Porter’s funeral began on Saturday, Combs honored Porter with an emotional note.

“Today we lay to rest our ANGEL,” he wrote on Twitter. “Her spirit lives on with us FOREVER!!! We thank you all for your prayers and support. You have no idea how much it means to us. We thank GOD for all of you.”

Insiders previously told PEOPLE that Combs, 49, held a memorial for Porter on Nov. 18 at his home in Bel Air, California. Among the 100 guests present were Kim Kardashian, Mary J. Blige, French Montana and Kourtney Kardashian.

On Nov. 15, officers were alerted after a woman was found unresponsive in Toluca Lake, California. She was declared dead at 11:40 a.m. local time. The Los Angeles County Sheriff’s Office confirmed Porter’s death in a statement.

According to an emergency dispatch call posted by TMZ, the call came in as a cardiac arrest. A source also told the outlet that Porter had been suffering from pneumonia for weeks.

A rep for Combs confirmed Porter’s death to PEOPLE at the time, saying, “Sadly, I can confirm the passing of Kim Porter. I ask that you give the families privacy at this time.”

Combs broke his silence for the first time after Porter’s death on Nov. 17, writing on Instagram, “For the last three days I’ve been trying to wake up out of this nightmare. But I haven’t.”

“I don’t know what I’m going to do without you baby. I miss you so much. Today I’m going to pay tribute to you, I’m going to try and find the words to explain our unexplainable relationship,” he added. “We were more than best friends, we were more than soulmates. WE WERE SOME OTHER S—!! And I miss you so much. Super Black Love.”

The couple began dating in the ’90s and had their three children throughout their on-and-off-again relationship.

Combs and Porter broke up in 1999 and battled in court over child support for Christian; Combs also dated Jennifer Lopez for two years before he and Porter reconciled in 2003. They split for the final time in 2007.

The day after Porter’s death, a source told PEOPLE: “Diddy is devastated and shocked. He and Kim were still very close friends and co-parents even though their romantic relationship didn’t work. They were still a family.”

Another source close to Combs said that he is “is very much struggling.”

“This is the most awful, sad and unreal situation for him. It’s a nightmare,” the source continued. “He isn’t sleeping. He always had a very special relationship with Kim. Despite not being together romantically, he loved Kim. It was really true love, and he is hurting badly right now.”

In 2017, Combs told PEOPLE that his children are all “really kind, great people.”

“They got a lot of love in their heart,” he said. “I’m the luckiest man in the world.”

The never-married Combs gave his children’s mothers most of the credit, though. “I’ve been truly blessed to have some great, incredible relationships that have afforded me these children by these very strong, intelligent, beautiful black women,” he said of his exes. “The mothers of my children [are] my best friends. My hat goes off to them.”
