Dionne Warwick has spoken out in defense of her sister Dee Dee Warwick and denied allegations that Dee Dee had molested Whitney Houston.

Last year, a documentary about Whitney saw her former assistant, Marie Jones, claim that the late singer had been molested by her cousin.

“All I can say about Dee Dee is that she was a loving, caring, giving person,” Warwick told PEOPLE. “What was depicted of her is absolutely untrue and something I will never forgive.”

Last year, Whitney's mother, Cissy Houston released the following statement:

"We cannot reconcile the Public’s need to know about Whitney’s life as justification for invasion of her privacy or the charge against Dee Dee, a charge which neither Whitney nor Dee Dee is here to deny, refute or affirm. Neither I, Dionne, nor my son Michael who was very close to his sister, and in the film is VERY candid about their drug use, has ever heard these allegations; we have never heard anything remotely connected to the crimes charged against Dee Dee in the film."
