Country superstar Blake Shelton paid a heartfelt tribute to his dear friend and fellow Oklahoma native, Toby Keith, following the singer’s peaceful passing at age 62 on Monday night.

In an emotional post on X (formerly Twitter), Shelton, 47, wrote, “Even though I knew about your battle these last few months, I never imagined this day would come. Anyone who ever met you understands what I mean. You were the toughest man I ever met.”

He continued, “Thank you, brother, for being a friend, a hero, and an inspiration. There will never be another Toby Keith.”

A Moment of Recognition

Last September, at the 2023 People’s Choice Country Awards, Shelton had the honor of presenting Keith with the Country Music Icon Award. At the time, Keith reflected on their long friendship, telling PEOPLE, “I’ve known Blake forever. He was on my first big headlining tour back when I earned that status, and I took him under my wing.”
