More than three months after Mac Miller's tragic death, fellow artist John Mayer has again paid tribute to the late rapper in a candid post on Instagram. In his note, Mayer lamented that he didn't get the chance to know Miller as well as he would have liked.

"Several weeks ago, I was sent an email asking if I wanted to take part in a Mac Miller tribute for a magazine as part of an end-of-year recap," Mayer, who collaborated with Miller on the track "Small Worlds," wrote. "I passed on it, not because I didn’t want to talk more about him, but because I couldn’t; I had shared all the memories I had of him in the brief time of our getting to know one another. I replied to the email and sat in silence for a few minutes."

He continued: "That day, I discovered a new dimension to the sadness of his passing - I wasn’t upset because I knew him well. I was upset because I didn’t. I wish I had more to tell you about Mac Miller. What I do have to remember him by are a couple of beautiful mental photographs that I’ll keep with me the rest of my life."

Miller died at age 26 of an accidental drug overdose. His received a posthumous Grammy nomination for his final album, Swimming, in December. Swimming is up for best rap album at the 2019 ceremony.

Mayer previously remembered Miller in a separate emotional post, in which he wrote, "You gotta know that if you weren’t familiar with Mac Miller, you were about to be, whether you would have seen him at a festival, or a friend was going to catch a show and tell everyone they knew about it (like I did). Mac put in the work. He made his best album and formed the band that was weeks away from becoming a breakout live sensation. Believe me when I say that."
