Whitney Houston's Funeral To Be Live Streamed

Houston sang at the church growing up; her family members including mother, Cissy Houston, and cousin, Dionne Warwick, are organizing the funeral.

Houston died Saturday at the Beverly Hilton hotel, at the age of 48. Her body was found "underwater and apparently unconscious" in a bathtub in her hotel room, police said. An autopsy was completed -- but the results are on security hold pending a toxicology report.

Her body was flown into Newark on Monday night in Tyler Perry's private jet; the casket was then transported to the Newark's Whigham Funeral Home, which is handling the services.

Earlier this week Davis -- Houston's longtime producer and father figure -- drew criticism from avant-garde musician Diamanda Galas, who wrote a scathing post on Facebook wherein she called him a "colossal pig" for putting the singer back onstage "before she was ready to perform." In a response Wednesday, a rep for Davis told THR: "Her Facebook post is wholly inaccurate and offensive."
