The entertainment mogul was dressed in a black tuxedo and overcoat as he made his way to Porter's funeral in Columbus, Georgia.
Porter's funeral is taking place today at the Cascades Hills Church where over 1,000 mourners are expected to be in attendance.
Diddy shared his feelings about the emotional day just before the funeral was to take place, writing, "Today we lay to rest our ANGEL. Her spirit lives on with us FOREVER!!! We thank you all for your prayers and support. You have no idea how much it means to us. We thank GOD for all of you. #KimPorter."
Kim Porter's family released a statement to the Associated Press ahead of her funeral, saying, "God broke the mold when he made Kim, there was truly no other woman like her. Although her time here on earth was far too short, she lived a life full of purpose and meaning. She was a loving mother and devoted friend. She was the epitome of kindness and grace. There wasn’t a person she met who’s soul she did not touch. Kim was the type of woman who changed lives for the better. She will be forever remembered and missed by so many. As her family, we promise to honor her every day of our lives. We love you always."
Porter — mother of three of Diddy's children — passed away suddenly last week at the age of 47.
