Debbie Nelson, the mother of famed rapper Eminem, has passed away at the age of 69 after a lengthy battle with lung cancer. A representative for Eminem confirmed her death on Tuesday, revealing that she passed away Monday night in St. Joseph, Missouri.

Eminem, born Marshall Mathers, has yet to publicly comment on his mother’s passing.

Nelson gained attention in popular culture through her portrayal in Eminem’s music, where he often referenced their troubled relationship. Songs like “My Name Is,” “Cleanin’ Out My Closet,” and “Headlights” depicted their turbulent history.

Despite the public nature of their issues, Nelson believed her son’s criticisms came from misunderstanding. In her 2008 memoir, My Son Marshall, My Son Eminem, she wrote, “In my heart, I know Marshall still loves me. He’s just confused.”

In 1999, Nelson filed a $10 million lawsuit against Eminem for defamation and emotional distress, stemming from his public remarks about her alleged drug use and abusive behavior. The lawsuit was eventually settled out of court, a matter Eminem referenced in his song “Without Me.”

Their relationship showed signs of reconciliation, particularly in “Headlights,” a 2014 track in which Eminem expressed regret over his past criticisms of his mother.

Born in 1955 on a U.S. Air Force base in Kansas, Debbie Nelson married Bruce Mathers in 1970 when she was just 15. She gave birth to Eminem two years later in St. Joseph, Missouri, before divorcing in 1974, citing physical abuse. After spending many years in Metro Detroit, Nelson returned to St. Joseph, where she spent her final days.
