Eminem just hit a special milestone.

After all, the Grammy winner shared that he has been sober for 16 years.

Eminem, whose real name is Marshall Mathers, posted a photo on Instagram April 20 of his recovery coin with the inscription, "Unity, service and recovery."

Loved ones couldn't help but share their excitement about the occasion, with longtime manager Paul Rosenberg writing, "Sweet 16. So proud of you." Younger brother Nathan Mathers commented, "Greatest Influence and Mentor."

Meanwhile, fellow artist John Mayer sent Eminem a fist bump emoji and singer-songwriter Bonnie McKee wrote, "Happy birthday!! 12 years for me!"

The "Lose Yourself" rapper has celebrated his sobriety over the years, including in 2020, which marked his 12th anniversary. "Clean dozen, in the books," he captioned the snap of his coin at the time. "I'm not afraid."

Eminem, who has been sober since 2008, previously shared that he had been addicted to Vicodin, Valium and alcohol.
