Lemmy Kilmister, the founding member and frontman of Motörhead, has died of cancer, according to the band's Facebook page. He was 70 years old.
The band writes the legendary rocker was diagnosed with cancer just two days ago.
"There is no easy way to say this…our mighty, noble friend Lemmy passed away today after a short battle with an extremely aggressive cancer. He had learnt of the disease on December 26th, and was at home, sitting in front of his favorite video game from The Rainbow which had recently made it's way down the street, with his family," the band wrote on Facebook.
They added, "We cannot begin to express our shock and sadness, there aren't words."
Born Ian Fraser Kilmister, the rocker was born in Staffordshire, England in 1945. He founded the band Motorhead in 1975 and was its sole remaining original member.
Motörhead has released 22 studio albums; their last, Bad Magic, was released in August 2015.
In an interview with USA TODAY earlier this year, the rocker said he originally envisioned Motörhead lasting "about six months. You don't actually think like that. You don't think, "We're going to last a thousand years."
Kilmister opened for Ozzy Osbourne on their first U.S. tour in 1981. Osbourne took to Twitter to express his grief late Monday.
"Lost one of my best friends, Lemmy, today," Osbourne tweeted. "He will be sadly missed. He was a warrior and a legend. I will see you on the other side."
