Billy Corgan has penned a touching tribute to his late friend, Scott Weiland, after learning of the former Stone Temple Pilots singer's death.

On Dec. 4, the Smashing Pumpkins frontman shared words about the "Creep" singer, who had been battling addiction for decades, on Smashing Pumpkins' website.

The 48-year-old wrote, "Having just woken to the news of this passing, I feel compelled to put pen to paper and pay my respects to Scott." The singer, who was a contemporary of Weiland's in the '90s, added, "And in that I will not pretend to know more than I know, or add some sad homily to how he loved his life. At least in that, may I now say he is undoubtedly in the arms of grace and eternal love."

The "Tonight, Tonight" singer added, "We mourn all that might have been. And as any fan, I find myself reflecting on what I do have: in scarce moments when Scott and I spoke as contemporaries and got to know each other as people… I'd try to make him giggle when I saw that the manic whirl of the dumb parties we were at (in Hollywood, no less!) might be causing undue stress."

On Dec. 3, Weiland was found dead on his tour bus in Minnesota. The troubled singer reportedly died of cardiac arrest hours before he was set to go on stage with his band, Scott Weiland & The Wildabouts. According to a police report, authorities found cocaine on Weiland's tour bus. The next day, Weiland's bandmate, Tommy Black, was arrested for possession of cocaine and booked for fifth degree felony possession of drugs. Reports have also been circulating that crack cocaine was a contributing factor in Weiland's death.

The late singer left behind a wife, Jamie Wachtel, and two children from a previous marriage.
