Celine Dion -- Drugs Killed Whitney Houston

Celine Dion isn't waiting for the coroner to give an official cause of death for Whitney Houston because she apparently knows what killed her ... drugs.

Speaking to "Good Morning America" today via phone, Dion wasted no time pinning Houston's untimely passing on drug abuse. She told Robin Roberts, "Whitney has been an amazing inspiration for me ... It's just really unfortunate that drugs, bad people or bad influence took over. It took over her dreams. It took over her love and motherhood."

Dion immediately linked Houston's death with other famous people who died from drugs. She went on to say, "When you think about Elvis Presley and Marilyn Monroe and Michael Jackson and Amy Winehouse, to get into drugs like that, for whatever reason. Is it because of the stress and bad influence? What happens when you have everything?"
