Sir Bob helped carry his daughter's coffin in the same church where just 18 months previously he had given her away at her wedding to Thomas Cohen. Peaches' mother Paula Yates was also laid to rest there in 2000.
He then bravely led the tributes to the tragic 25-year-old at St Mary Magdalene and St Lawrence church in the village of Davington, near Faversham in Kent.
Record label boss Alan was present at the funeral service for mother-of-two Peaches, and told the Mirror he was particularly moved by Bob's bravery.
"It was very heavy when I saw Bob help carry his daughter down through the chapel," he said of the ceremony, which took place on Easter Monday.
"It was incredibly tragic but I think he handled it as well as any man could.
"The bravest thing I think I’ve ever seen him do is give the eulogy to his daughter who has died."
Peaches passed away on 7 April at her home in Wroxham, Kent. The cause of her death is still unknown.
She leaves behind two young sons Astala, 23 months, and Phaedra, 11 months, with her musician husband Thomas.
Mourners at her funeral included sisters Fifi, Pixie and Tiger-Lily, Kate Moss, Sarah Ferguson, Alexa Chung, Johnny Borrell, and Jools Holland.
Peaches' ashes were said to have been scattered at her father's neighbouring Davington Priory country estate, where she grew up.
