Kim Porter, ex-girlfriend and mother of Diddy's children has died. She was 47 years old.

The sudden The death last week of Kim Porter, Diddy's ex girlfriend and mother of three of his children, remains a mystery after the Los Angeles coroner's office reported that an autopsy could not immediately establish the cause of death.

Sarah Ardalani, a spokeswoman for the Los Angeles County coroner and medical examiner's office, said Monday that an autopsy was performed on Friday.

"The cause of death was postponed pending further tests," Ardalani said in an email to USA TODAY. He added that Porter's body has been delivered to his family.

The 47-year-old model and actress was not answered on Thursday at her home in the San Fernando Valley city area. She was pronounced dead at home, according to the coroner.

At that time, the Los Angeles Police Department said no foul play was suspected.

A final conclusion about why a relatively young woman would die suddenly may take weeks to respond.

Diddy, born Sean Combs and Porter were no longer a couple, but they were still around, sharing three children: their son Christian, 20, and his twin daughters D & # 39; Lila Star and Jessie James, who will turn 12 next month. They also raised Quincy Brown, 27, son of Porter with singer and producer Al B. Claro.

Combs has been devastated by his death, speaking for the first time on Sunday calling the days since his death a "nightmare."

"For the last three days I've been trying to wake up from this nightmare, but I have not," he wrote on Instagram. "I do not know what I'm going to do without you, baby, I miss you so much."
