Saturday’s invitation-only private funeral for Whitney Houston is turning into the media circus her family wanted to avoid — or did they? Kevin Costner, Houston’s co-star in “The Bodyguard,” and mentor Clive Davis will speak at service; Aretha Franklin and Stevie Wonder will perform, reports People. (It now looks like Houston’s ex-husband, Bobby Brown, will attend.) Bowing to public pressure, the singer’s publicist announced that the noon service will be broadcast and streamed online from the New Hope Baptist Church in Newark, where Houston sang as a child. And Gov. Chris Christie has created a firestorm with his decision to lower flags to half-staff on government buildings Saturday — critics say the honor should be reserved for troops and public servants. Christie defended his choice, calling Houston one of the state’s “cultural icons” like Frank Sinatra and Bruce Springsteen and saying he was disturbed by those who believe her drug abuse “forfeited the good things that she did in her life. I just reject that on a human level.”
