Sean "Diddy" Combs has broken his silence about the death of his ex Kim Porter. As Entertainment Tonight reports, the rapper shared an emotional Instagram post on Sunday about 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," Diddy captioned a video of a pregnancy photo shoot with Porter and wrote. "I miss you so much. Today I'm going to pay tribute to you, I'm going to try to find the words to explain our unexplainable relationship. We were more than best friends, we were more than soulmates. We were some other sh**!! And I miss you so much. Super Black Love." Porter died suddenly last week after battling pneumonia for several weeks.
