Friends and relatives of US singer Whitney Houston are gathering in Newark, New Jersey, for her funeral.
Some 1,500 guests will attend the private ceremony at the New Hope Baptist Church. Houston's body will then be buried at a local cemetery, alongside her father.
Security will be tight, with fans kept away, although the funeral service will be streamed live on the internet.
Houston, 48, was found dead in a hotel in Los Angeles a week ago.
Officials are waiting for the results of toxicology tests that will help them ascertain how she died.
The New Hope Baptist Church is where a young Whitney Houston sang in a gospel choir run by her mother.
The 1,500 invited guests will include some of the biggest names in show business.
Stevie Wonder and Aretha Franklin will sing, while Kevin Costner, who starred opposite Houston in The Bodyguard, will be one of the speakers, as will Clive Davis, her musical mentor.
There will also be contributions from Houston's cousin Dionne Warwick and singer Alicia Keys.
Houston's ex-husband Bobby Brown will also attend, with the couple's only child Bobbi Kristina.
The BBC's Michelle Fleury in Newark says there has been a lot of debate about his attendance because of the well-publicised problems of the couple's marriage, and also talk about how much time he will spend with his daughter.
The ceremony will also be streamed on the BBC News website at 12:00 EST (17:00 GMT).
Houston will then be buried beside her father, John Russell Houston, at Fair view Cemetery in Westfield.
