Loved ones say goodbye to Whitney Houston NEWARK, N.J. - Whitney Houston's flower-covered casket arrived Saturday at the church where her powerful voice first wowed the congregation, as the biggest names in entertainment solemnly filed in to remember the pop superstar in her hometown. Mourners at the New Hope Baptist Church fell quiet as three police officers escorted Houston's silver casket, draped with white roses and purple lilies. White-robed choir members began to fill the pews on the podium. As the band played softly, the choir sang in a hushed voice, "Whitney, Whitney, Whitney." Family prepared a service where singer Dionne Warwick, Houston's cousin, music mogul Clive Davis, who shepherded Houston's career for decades, actor Kevin Costner and sister-in-law Patricia Houston were to speak. Stevie Wonder, Alicia Keys, R. Kelly and gospel stars CeCe and Bebe Winans were to sing. Houston's voice, a recording of her biggest hit, "I Will Always Love You," was to close the funeral. Close family friend Aretha Franklin, whom Houston lovingly called "Aunt Ree," had been expected to sing at the service, but she was too ill to attend. Franklin said in an email to The Associated Press that she had been up most of the night with leg spasms and sent best wishes to the family; "May God bless and keep them all," she wrote. Pictures: Whitney Houston memorial Singers Chaka Khan, Brandy, Roberta Flack, Jordin Sparks and Jennifer Hudson were among those filling pews. Brandy comforted her brother, Ray-J, a singer who spent time with Houston during her final days. The Rev. Jesse Jackson and actor Lela Rochon were also gathering as the choir began to sing gospel and the congregation clapped. A program featuring a picture of Houston looking skyward read "Celebrating the life of Whitney Elizabeth Houston, a child of God." Pictures of Houston as a baby, with her mother, gospel singer Cissy Houston and daughter, Bobbi Kristina filled the program. "I never told you that when you were born, the Holy Spirit told me that you would not be with me long," Cissy Houston wrote her daughter in a letter published in the program. And I thank God for the beautiful flower he allowed me to raise and cherish for 48 years. "Rest, my baby girl in peace," the letter ends, signed "mommie."
