About 1,500 guests are expected to attend a private service for Whitney Houston held in her hometown, Newark, New Jersey, Saturday.
"Whitney really made us proud," said Gee Cureton, a Houston fan. "Her voice was electrifying, and she was a great, great singer. She was one of the best of all times."
The ceremony will feature performances by Alicia Keys, Stevie Wonder and Whitney Houston's godmother, Aretha Franklin.
Actor Kevin Costner, Houston's co-star in the 1992 hit movie The Body Guard, will speak at the service.
Fans of the pop star have been leaving balloons, candles and messages to the singer in front of new Hope Baptist Church, --- the site of the funeral and the church where Houston sang as a child.
"I just wanted to be supportive and show love to the family," a fan said.
New Jersey Governor Chris Christie ordered flags to fly at half-staff to honor Houston.
"Whitney Houston was an important part of the fabric, the cultural fabric of this state," Christie said.
Meanwhile, toxicology reports that may determine what caused the 48-year-old's death are not back yet.
Sources close to the investigation say the singer was drinking heavily in Beverly Hills, in the days before her death.
Houston's funeral service will be streamed live on KDVR.com beginning at 10AM.
