“Pawn Stars” lead Rick Harrison revealed his son Adam, 39, died from a fentanyl overdose.

“Yes, I can confirm Adam died from a fentanyl overdose,” Harrison, 58, told The Post in a statement on Monday, after Adam’s cause of death was first reported by TMZ.

“The fentanyl crisis in this country must be taken more seriously,” he added. “It seems it is just flowing over the borders and nothing is being done about it. We must do better.”

His rep said Adam died in Las Vegas and the family was notified Friday.

Harrison broke his silence on Adam’s death on Instagram the same day.

“You will always be in my heart!” Harrison wrote beneath a photo that showed him smiling alongside his look-alike son in a bar. “I love you Adam.”

Adam’s brother, Corey, also penned an Instagram tribute, sharing an old baby picture of the two of them in a bathtub.

“Wax wtf I will always love you bubba,” he captioned the throwback photo.

Rick had Adam and Corey, 40, with his first wife, Kim. He also has a third son, Jake, with his second wife, Tracy.

TMZ was the first to break the story of Adam’s death.

Since 2009, “Pawn Stars” has documented the multigenerational Harrison staff at their Las Vegas Gold & Silver Pawn Shop, in which they authenticate objects brought into the store and make the seller an offer.

Adam never appeared on the History Channel show, TMZ reported, and had reportedly stepped away from the pawn shop. Other than Rick’s tribute post, Adam is noticeably missing from Rick’s Instagram, which features snaps of other family members.
