Ian 'Lemmy' Kilmister, frontman and founder of British heavy metal band Motörhead, died at the age of 70 two days after learning he had cancer.
The band said that Kilmister was diagnosed with cancer two days after his birthday and passed away at his home in Los Angeles.
Ozzy Osbourne tweeted: "Lost one of my best friends, Lemmy, today. He will be sadly missed. He was a warrior and a legend. I will see you on the other side."
The Facebook post read: '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 its way down the street, with his family."
"We cannot begin to express our shock and sadness, there aren't words. We will say more in the coming days, but for now, please...play Motörhead loud, play Hawkwind loud, play Lemmy's music LOUD. Have a drink or few."
Tributes have been coming in for Kilmister from well-known artists within the rock and metal community following his death on December 28.
