Reports are coming in via social media and other news outlets that Ian Fraser "Lemmy" Kilmister of the heavy metal band Motorhead has passed away. He was 70.

According to the website Consequence of Sound, "Lemmy had been suffering from a number of well-publicized health issues, including hematoma and had been fitted with an implantable defibrillator to correct an irregular heartbeat."

He celebrated his 70th birthday on Christmas Eve with a party that included other all-stars such as Billy Idol and members of the bands Guns N' Roses and Metallica.

Motorhead is best known for rock songs like Ace of Spades, Overkill and Iron Fist. Lemmy helped form Motorhead (initially called "Bastard") in 1975.

While the official Motorhead social media accounts haven't yet confirmed the news, several other stars and musicians have been tweeting their condolences.
