P. Diddy's pet dog has died.

The 44-year-old rapper - whose real name is Sean Combs - has been left devastated following the passing of his beloved golden-haired pooch, Honey, yesterday (18.04.14).

Diddy broke the news on Instagram last night after posting a picture of the adorable dog with the caption: ''Today was one of the saddest days of my life. I said goodbye to my dog Honey. Who was always there for me. #RIPHoneyCombs love you and you are missed already (sic)''.

However, the 'Last Night' hitmaker's heartbreak didn't stop there though as he shared another snap of him lying on the grass staring into the canine's eyes, just two hours later.

He accompanied the photograph with the caption: ''GOODBYE MY FRIEND!!!!! #HoneyCOMBS RIP! To whoever has lost a Pet I feel your pain! I thank God for givin me a friend like you ! (sic).''

Meanwhile, Diddy - who has five children from previous relationships - topped Forbes' list of the five wealthiest artists in hip-hop this year - beating Jay Z and Dr Dre - with a worth of $700 million, but it seems no amount of money could take away the pain of losing his dog.
