Kim Porter is being laid to rest in her hometown of Columbus, Georgia today.
An emotional Diddy took to Twitter to thank fans for their "prayers and support" as he attends the funeral.
"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," he tweeted.
According to TMZ , he’s expected to deliver a eulogy at the funeral but may bow out because of his "fragile emotional state".
After a funeral expected to be attended by 1,200 to 1,500 mourners, Kim will be buried next to her mother Sarah Lee Porter who died in 2014.
Diddy, 49, said he and his ex-partner were "more than soulmates" and went to visit her one last time at a private viewing yesterday.
Model Kim was 47 when she was found dead at her home in Toluca Lake, California.
In a statement, that the families of Diddy and Kim issued ahead of the funeral, she was described as ‘truly like no other woman’.

The emotional words of the joint statement were: "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. Although we’ve lost our best friend, God has gained a special angel and we know she is watching over us."

The statement continued: "She will be forever remembered and missed by so many. As a family, we promise to honor her every day of our lives. We love you always. The Porter, Goodwin and Combs families."

The actress and model, 47, was found dead at her home in Toluca Lake, California, on the morning of November 15.
