Family, friends and a host of famous faces are due to attend the funeral of singer Whitney Houston, which will take place in her home state of New Jersey on Saturday.

They will gather for a private service at New Hope Baptist Church in Newark, where Whitney sang as a child – before she is buried next to her father John Russell Houston at Fairview Cemetery in her home town of Westfield.

Actor Kevin Costner – who co-starred with her in the 1992 film The Bodyguard – is among those scheduled to speak at the service, while her cousin Dionne Warwick and godmother Aretha Franklin are among those who will perform.

However it remains unclear whether her ex-husband Bobby Brown – father of Whitney’s 18-year-old daughter Bobby Kristina – will be at the service following reports he had not been invited.

Although the ceremony will be a private, invitation-only affair, fans have been gathering outside the church to lay flowers and tributes.

The singer’s family will also allow a single camera inside the church to film the service, which will be streamed online, while footage will also be shown on Sky News.

Investigations are continuing into the death of the 48-year-old, who was found underwater in a bathtub at the Beverly Hilton hotel in Los Angeles last Saturday.

Sales and downloads of some of her greatest hits – which included I Will Always Love You, I Wanna Dance With Somebody, I Have Nothing and The Greatest Love Of All – have soared in the days following her death.
