The hearse carrying Whitney Houston's casket has arrived at the New Jersey church where her funeral is being held.
About 1,500 people were invited to the service at New Hope Baptist Church in Newark. Houston sung in the church choir there as a child.
Houston died on February 11 in California, the day before the Grammy awards. She was 48.
A gospel choir was rehearsing in the church hours before the service, and roses and lilies surround the pulpit.
Aretha Franklin is no longer planning to sing at the funeral.
She had been expected to sing. A person close to the Houston family said Franklin is no longer planning to attend because she is sick.
Franklin performed on Friday and was scheduled to give another concert on Saturday night.
A revised programme for the service lists Stevie Wonder, Alicia Keys and R Kelly among those who will sing.
The guests will include music mogul Clive Davis.
After the funeral, Houston is scheduled to be buried beside her father, John Russell Houston, at Fairview Cemetery in Westfield, near where she grew up.
