Bobbi Kristina's estate has now joined forces with Bobby Brown to stop TV One from doing a biopic on Bobbi Kristina's life.
Bobby Brown has already filed a suit, claiming the portrayal as a bad dad is defamatory.
Bobbi Kristina's estate has now joined the lawsuit, claiming the biopic violates Bobbi Kristina's right to privacy.
Bobby Brown has already claimed in his lawsuit that the movie falsely shows him as a violent person toward Whitney Houston.
The show suggests Bobbi Kristina witnessed the alleged abuse and has scenes showing him as an unloving father.
The estate and Bobby Brown want more than $2 million in damages and they want the judge to block the airing of the show.
The show is set to air on TV One next month.
