Model, actress, and singer Kim Porter, who dated and shared three children with rap mogul Sean ‘Diddy’ Combs, died at the age of 47.

On Thursday morning, Porter was found in her Toluca Lake home in Los Angeles. According to the Los Angeles County medical examiner’s office, officers arrived at her home at 11:40 a.m., where they found her unresponsive and was later pronounced dead at the scene.
