Duke Gadd's Mother Blasts Corey Feldman Over Comments on Son's Death

Duke Gadd‘s mother is not happy with Corey Feldman … ’cause the coroner hasn’t ruled on her son’s death yet — so, she doesn’t know how “Dr. Corey” can tell everyone he knows how Duke died.

We spoke with Carol Gadd — Duke’s mom and wife of legendary Steely Dan drummer Steve Gadd … and, she tells us they haven’t received a coroner’s report yet, so her son’s cause of death isn’t official.

She says the family was told he had a heart attack — and a drug was probably involved … but, no one they talked to has said it was for sure a fentanyl overdose.

Carol says her son subbed in Corey’s group for a few gigs after his last drummer bailed on the tour … so, Duke and Corey definitely knew each other. But, “Dr. Corey” — as she sarcastically calls him — isn’t qualified to claim he knows the exact nature of Duke’s death.

Gadd adds Corey’s posts are especially painful because official word hasn’t come out … so, sounds like Feldman’s really upset the family.

As we told you … Corey told his fans Duke died from a fentanyl overdose in an IG post — showing pics of DG on the drums during the tour. He said Duke was “poisoned by his own struggles in life” and died far too young.
