P Diddy Shares Regret Over Not Marrying Late Ex Kim Porter

In a touching throwback photo posted to Instagram on Sunday, P Diddy shared an adorable and gut wrenching tribute to his former girlfriend, Kim Porter.

The old picture shows the rapper and model cuddled up on a couch, with Kim's arms lovingly wrapped around Sean's head.

'SMH,' Diddy, 49, captioned the photo. He added a broken heart symbol next to the sad message. SMH is internet slang for Shaking My Head.
