Friends of Whitney Houston -- who are peddling a documentary film on her life -- claim Whitney was molested by Dionne Warwick's sister, singer Dee Dee Warwick.
Dee Dee is not around to defend herself; she died in 2008 at age 63 following a long illness.
Dee Dee is Whitney's cousin and the younger sister of pop legend Dionne Warwick, the family member who had the most influence on Whitney's music career.
The documentary "Whitney" premiered at Cannes film festival on Wednesday night and the filmmakers waited until the end of the film to drop the shocking claim that the legendary singer was molested by her cousin at a young age.
Mary Jones, a longtime assistant to Houston, revealed in the documentary that Whitney told her Warwick had molested her.
"It made her question her sexual preference," Jones told Entertainment Weekly.
In her 2013 book, "Remembering Whitney", Cissy Houston, gospel singer and Whitney's mother, makes no mention of molestation claims.
"I think she was ashamed," Jones said of why Whitney never told her mother. "If Cissy had known, she would have done something about it, because Cissy loves her children."
Cissy does mention Robyn Crawford, Whitney's best friend and personal assistant, who may or may not have been involved in a romantic relationship with Whitney.
It was Robyn who told Cissy about her daughter's drug problems. Cissy would later say she respected Robyn for that.
Whitney died of an accidental drowning at age 48 on Feb. 11, 2012 in a Beverly Hills hotel bathtub.
Her pop single "I Will Always Love You" is the fifth best-selling single in the world with certified sales of 20 million.
