London: Whitney Houston's mother is planning to write a tell-all book about the legendary singer.

Cissy Houston, 78, vowed it would set the record straight on her daughter, who drowned in a bath at a Beverly Hills hotel aged 48, as reported.

"I want to stop the lies, It's going to be the bad. It's going to be the good," Cissy said.

Cissy has met several publishers in New York. A deal could reach seven figures depending on what she reveals about the diva's drug and marriage woes.

Two of the publishers said she was reluctant to address the issues.
