Whitney Houston’s funeral is scheduled for tomorrow in Newark, New Jersey. The invitation-only event will reportedly be broadcast on the Internet for her fans, since there will be no public memorial service. Many famous celebrities will be paying tribute to the songbird, who died on Saturday in her Beverly Hills’ hotel room.

Talk show queen Oprah Winfrey, hip-hop power couple, Jay-Z and Beyonce, and music legends Stevie Wonder, Aretha Franklin, Elton John and David Bowie are among the big names expected to attend Houston’s invitation-only funeral at the New Hope Baptist Church. Wonder and Franklin are expected to sing at the service, along with Alicia Keys and R. Kelly. Actress Angela Bassett, actor Kevin Costner, actor-director Tyler Perry, and TV legend Bill Cosby are among the other stars said to be attending Saturday’s service.

And despite earlier reports that indicated otherwise, Bobby Brown is being invited to the funeral. TMZ.com is citing Houston family sources who say Whitney’s ex-husband has been asked to attend this weekend’s ceremony. One insider says the family decided that inviting Bobby “would keep the peace at the funeral.” It was previously reported that some of Whitney’s closest loved ones don’t want Bobby to attend, because they feel he’s to blame for her downfall, particularly her drug and alcohol addictions.

However, Houston once said in her infamous 2002 interview with Diane Sawyer, “the biggest devil is me.”

Meanwhile, investigators are looking into doctors who wrote multiple sedative prescriptions, as they try to determine the cause of the pop superstar’s death. The coroner said that even though the autopsy was complete, the results would not be finalized until he received the toxicology reports, which could take up to eight weeks.
