Not only is Bobby Brown not banned from attending Whitney Houston
's invitation-only funeral on Saturday, he is performing with New Edition a few hours later, it was just announced.
"He is not being banned. That's completely untrue," a family source tells PEOPLE.
Adds a close family friend: "Bobby will be there at the funeral to support his [and Houston's] daughter [Bobbi Kristina Brown, 18]. There was some talk ... some people were angry at him, but that's just grief. He will be there."
But Houston's funeral isn't Brown's only obligation on Saturday. Hours after his ex-wife is buried in New Jersey, he will perform with all the original New Edition members at Connecticut's Mohegan Sun Arena, a rep for the venue confirms.
Early Thursday, PEOPLE learned that Clive Davis, Aretha Franklin, Stevie Wonder and Kevin Costner will be among the speakers
and singers at the funeral, which is being held at the New Hope Baptist Church in Newark, where Houston's distinctive voice was first heard in the choir.
"Kevin always supported her and, like many of her friends, they may have lost touch, but they were always friendly," says the family friend.
Friday night, a private family service is planned.
Earlier this week, Houston's publicist, Kristen Foster, said that the only video camera to be permitted inside the church for the funeral will be that belonging to the Associated Press, which will stream the service on its Livestream site
and on PEOPLE.com.
Brown, now 43, and Houston wed in 1992, and the following year Brown was charged with domestic abuse, though the charges were later dropped. After several rocky years together, the couple divorced in 2007.
Houston, 48, was found dead Saturday
in the bathtub of her suite
at the Beverly Hilton Hotel, and her body was returned to New Jersey
