Model Kate Moss and former Rolling Stones bassist Bill Wyman were among those attending the private service today at a village church in Kent, southern England.
The church is the same where Geldof married her second husband Tom Cohen. It is also where the funeral of her mother, Paula Yates, was held when she died of accidental drug overdose in 2000.
It is not yet known what caused the sudden death of Geldof, who was found at her home on April 7.
