Nov. 18 (UPI) — Music mogul Sean “Diddy” Combs shared a video on Instagram on Sunday of Kim Porter, his late ex-girlfriend and the mother of three of his children.

“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. We were more than best friends, we were more than soulmates. WE WERE SOME OTHER (expletive)!! And I miss you so much. Super Black Love,” Combs wrote alongside the short film of him and Porter in happier times.

Porter died Thursday at the age of 47.

An autopsy was conducted, but the cause of death was deferred pending further testing. She reportedly had been sick with the flu or pneumonia in the days before she died.
