Kim Porter, who dated rapper Diddy and is the mother of three of his children, is believed to have gone into cardiac arrest on Thursday at noon. She had been suffering from pneumonia for several weeks. However, the official cause of death is still unknown.

Diddy and Kim dated for 13 years from 1994 to 2007. A representative for Diddy has said, "Sadly, I can confirm the passing of Kim Porter. I ask that you give the families privacy at this time."

Kim had four children. She and Diddy have Christian Combs, and twin girls Jessie James and D’Lila. Kim also has a son, Quincy, from a previous relationship.

Kim grew up in Columbus, Georgia, and featured in The Notorious B.I.G documentary 'Can't Stop, Won't Stop: A Bad Boy Story.'
