Sean “Diddy” Combs is working through his grief after the death of his ex-girlfriend Kim Porter.

Porter, who raised four children with Combs, was found dead on Thursday at age 47.

After breaking his silence with a video of the former couple dancing and canoodling for the camera while the model was pregnant, Combs shared a peek at a private memorial he held for Porter on Sunday afternoon. A source tells PEOPLE mourners included Pharrell Williams and Kourtney Kardashian, while TMZ reports Mary J. Blige and French Montana were also in attendance.

In the Instagram story videos, Combs surveyed six glamorous photos of Porter set up on easels outside a home. On the ground, candles burned.

Alongside a breezy snapshot of Porter grinning behind the wheel of a boat, Combs dropped five hearts.

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

Her health status was described as a cardiac arrest in an emergency dispatch call obtained by TMZ. A source told TMZ that she had been battling pneumonia.

“Diddy is devastated and shocked,” a source previously told PEOPLE. “He and Kim were still very close friends and co-parents even though their romantic relationship didn’t work.”

“They were still a family,” the source continued.

Combs and Porter, who dated on and off from the ’90s through 2007, share a 20-year-old son Christian and 11-year-old twins D’Lila Star and Jessie James. Combs, who has two kids from other relationships, considers Porter’s 27-year-old son Quincy his own.

Today I’m going to pay tribute to you, I’m going to try and find the words to explain our unexplainable relationship.”

“We were more than best friends, we were more than soulmates,” he concluded. “WE WERE SOME OTHER S—!! And I miss you so much. Super Black Love.”
