Corey Feldman is mourning the death of his Love ReTours drummer, Duke Gadd. He shared the sad news on Instagram, revealing the young musician died of a fentanyl overdose.

"It’s with tremendous sadness I must relay the news that our drummer from the #loveretours23 tours has passed away @ a very young age!” Feldman captioned a carousel post showing photos and videos of Duke. “Our friend & drummer @melomaniac_graffiti aka #dukegadd passed away in Vegas yesterday from a fentanyl overdose!”

"He was beyond talented and had a gr8 heart but was poisoned by his own struggles in life," the actor/musician continued. "What a tremendous loss of a talented young man gone far 2 soon! My heart hurts losing another friend 2 the throws of drug addiction & the insane fentanyl crisis that’s taken over our country! my condolences 2 all his friends & family! #ripdukegadd”

Duke was the son of legendary studio and session drummer Steve Gadd.

Feldman has had his own struggles with drug addiction. As Us Magazine points out, the former child actor spoke about his struggles and being sexually abused as a teenager in a 2013 interview. "And that’s when I really took the plunge, after I got off the coke, after I’d already had a stint with crack,” he recalled at the time. “Then this other girl broke up with me, and then the guy, who was the pedophile … who introduced me to every one of the drugs I ever tried said, ‘Hey, why don’t you try heroin.'”

In 2016, Feldman revealed he was more than two decades sober.
