Legendary rocker Alice Cooper has paid tribute to David Bowie, who died on Sunday, two days after his 69th birthday.
"It's hard to know exactly what to say when you hear of someone's passing," Alice said. "I know that I have certainly lost one of my lifetime rock and roll theatrical comrades in David Bowie. We both started in theatrical rock 'n' roll at the same time, and in some cases we challenged each other to go farther and push the envelope."
He continued: "The loss of David Bowie will be hard to swallow for everyone. He leaves behind a rich history of musical and cultural experimentation and invention that will rarely be seen again, if ever. He was one of a kind.
"The man that fell to Earth has gone back to the planet that he came from.
"Condolences to his family and fans."
Bowie died just three days after releasing his 25th studio album, "Blackstar".
The singer, songwriter, actor and fashion icon reportedly kept his 18-month battle with cancer so private that even close friends weren't aware of his struggle.
In the early Seventies, Bowie was occasionally accused of borrowing from Cooper's onstage persona. "I kind of expected all that to happen, and I just trusted in my own conceptions that eventually we'd split off and have separate identities, Alice and myself," Bowie said in a 1977 interview. "I just trusted in my optimistic ideas of what I could do."
