As reported by AOL Music, ever since Whitney Houston's untimely death on the eve of the 2012 Grammys (Feb. 11), there have been talks about a biopic based on the late legend's life and speculation about who should portray her in the film. Rihanna recently told The Press Association she would "love" to play Houston in an upcoming movie, admitting, "That would be something that I would have to give my entire life to do because I would want to really pull it off."

However, there is reportedly one very important person who is absolutely not a fan of casting RiRi in the role -- Whitney's mother, Cissy Houston!

"Over my dead body!" a 78-year-old Cissy said of the idea, according to a National Enquirer source. "Cissy does not think Whitney should be represented by some­one like Rihanna," the source revealed. "Cissy believes Rihanna cel­ebrates everything she hated about Whitney's life -- the drugging, the boozing, the abusive relationship."

The 24-year-old pop star is known for her hard-partying ways. Ri is frequently photographed leaving nightclubs in the wee hours of the morning, and is quite vocal about her weed-smoking habits on Twitter. Whitney, who battled drug addiction for years, died with cocaine both in her system and all over the Beverly Hills hotel room where her body was found.

As for the similarities in their tumultuous love lives, Houston was married to the physically and emotionally abusive Bobby Brown, who many speculate was responsible for encouraging her drug habit. Rihanna, of course, has reconciled with her own abusive ex Chris Brown, who infamously beat her back in 2009.

Despite Whitney's highly publicized troubles, Cissy wants any future film about her daughter to tell the story of her triumphs as well. "In spite of what anyone thought about Whitney, she sees her as a God-fearing Christian who loved the Lord," the source said.
