The late Whitney Houston's family is not supporting Lifetime's highly anticipated biopic on the legendary singer.

On Tuesday, Whitney's mother Cissy Houston told ET exclusively that the family is "exhausted" by the "continuing misinformation and comments offered by people who did not know her," and pleaded with fans to "please let her rest."

"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 Bobby," she said in a statement to ET. "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."

Directed by actress Angela Bassett, the biopic will feature Houston's music, but not her voice -- R&B singer Deborah Cox will provide the vocals for her hit songs.

Houston and Brown's daughter Bobbi Kristina, 21, has also been outspoken about her disapproval for the upcoming film, specifically, not being cast by Bassett to play her mother. She has since deleted the tweets she posted blasting Bassett.
