Whitney Houston, who passed away last Saturday at age 48, will be memorialized today at a funeral service held at the New Hope Baptist Church in Newark, N.J., the singer's birthplace. The service begins at noon ET and will be streamed live across the internet. Scheduled to appear are Clive Davis, currently facing heavy criticism for having not canceled his Grammy party the night of her death; and her The Bodyguard costar Kevin Costner, who in a 20/20 interview on ABC last night said it was he who suggested she cover the Dolly Parton song "I Will Love You," against the advice of her handlers. The song would go on to become the biggest-selling single for a female artist in history. Also scheduled to appear is Stevie Wonder, who will sing. 

The streaming has already begun: A choir of dozens of female singers, dressed in white, are clapping and singing an uplifting spiritual, accompanied by a seven-member band.

UPDATE: Ex-husband Bobby Brown left the funeral 15 minutes into the ceremony, the NY Daily News reports. Rev. Al Sharpton tweeted:

I am at Whitney's funeral. I spoke with Bobby Brown trying to calm him down and not distract from the services. Today is about Whitney!

Minutes later, he wrote:

I am going back in the services, I did my best out here. Can't tweet from inside the sanctuary, I hope the press will not distort the day.
