Whitney Houston's star-studded sendoff will reportedly feature the soulful, soaring voices of her godmother, Aretha Franklin, Stevie Wonder and Alicia Keys. 

Among those expected to speak at the funeral on Saturday are Kevin Costner, her co-star in The Bodyguard, Houston's mentor, Clive Davis, and her cousin, singer Dionne Warwick.

Guests set to attend the invite-only service at the New Hope Baptist Church in Newark, New Jersey, include Oprah Winfrey, Tyler Perry, Bill Cosby, Chaka Kahn, Brandy, Beyonce, Jay-Z and Ray J, a hip hop singer who has been linked romantically to Houston.  

The fond farewell to the fallen star will be broadcast online.  

According to her death certificate, Houston will be laid to rest at the Fairview Cemetery in Westfield, New Jersey, where her father is buried.
