Whitney Houston's mum Cissy Houston has slammed an upcoming Tv biopic about the late singer, calling on filmmakers to "let her rest".

Actress Angela Bassett, who co-starred with Houston in 1995's Waiting to Exhale, is planning to make her directorial debut with I Will Always Love You: The Whitney Houston Story for America's Lifetime network.

However, she does not have support from Houston's mum, who has now spoken out against the made-for-Tv movie.

A statement to Entertainment Tonight reads, "Lifetime has chosen to go ahead with the movie about Whitney in spite of my family's objections.

"No one connected with this movie knew Whitney or anything about her relationship with (ex-husband) Bobby (Brown). In the two years since Whitney's death, many people have stepped forward to speak about their close relationship with her. I find it difficult to believe people who knew and supposedly loved her would participate in a movie about her done by folks who didn't know her.

"We are exhausted by the continuing misinformation and comments offered by people who did not know her. Please please let her rest."

While the release date for the movie has yet to be revealed, the main cast has already been made public - former America's Next Top Model contestant Yaya DaCosta is set to play Houston, R&B singer Deborah Cox will provide the vocal tracks, and Final Destination 5 star Arlen Escarpeta will play Brown.
