A star-studded lineup will sing and speak at pop star Whitney Houston’s funeral, from Alicia Keys and Kevin Costner to the soul and gospel music royalty from which she hails, including her cousin Dionne Warwick and Aretha Franklin. Houston will be laid to rest on Saturday after an invitation-only memorial service at the New Hope Baptist Church in Newark, New Jersey, where Houston groomed her voice singing in the church choir with her mother Cissy Houston, a soul and gospel singer who once backed up Franklin. Other top names taking part in the service include Houston’s mentor and record producer Clive Davis, singer Stevie Wonder and Hollywood actor and producer Tyler Perry, who donated his plane to fly her body from Los Angeles to Newark earlier this week. Elton John, Beyonce and rapper Jay-Z, Oprah Winfrey and Bill Cosby are also expected to attend, according to reports. The singer rose to fame with a soaring voice and hits in the mid-1980s such as ‘Saving All My Love For You’. It is not yet known if singer Bobby Brown will be there.
