At the Whitney Houston funeral, ABC News reportst that Bobby Brown left the church and drove off with his son Landon and daughter LaPrincia in a black Cadillac Escalade. The highlight of the funeral so far is when Kevin Costner took the stage and elicited some laughs while cracking jokes about sneaking into church as a child and casting Whitney in The Bodyguard. He signed off saying "Off you go," and that when Whitney sings in front of God she shouldn't worry because she'll be "good enough." After a visibly emotional Alicia Keys sang, Mentor Clive Davis said of Whitney, "You wait for a voice like that for a lifetime." Though it’s a private invitation-only funeral, is being livestreamed across the globe Saturday from the New Hope Baptist Church, Houston’s childhood church. Aretha Franklin is no longer singing during the service due to a sudden illness.
