Dave Grohl's gone on record as saying Lemmy is the "king of rock 'n' roll," and now he's given the dearly departed Motörhead frontman a tribute befitting a king.

As Grohl told fans through the Foo Fighters' official social media accounts, he was left gutted in the wake of Lemmy's passing on Dec. 28. "We’ve lost a friend & legend. My heart is broken," reads a post sent out in his honor. "RIP Lemmy. Born to Lose, Lived to Win."

But words weren't enough for Grohl, who had the opportunity to socialize and collaborate with Lemmy after idolizing him for years, and felt honored to call him a friend. Wanting to express that love in a way that was fittingly rock 'n' roll and pretty much permanent, he did the natural thing and headed over to a tattoo parlor, where he had some "Ace of Spades" ink emblazoned on his inner wrist.

Grohl's bond with Lemmy bore creative fruit on a number of occasions, with the two sharing a stage repeatedly over the years and working together in the studio for Grohl's Probot project, which enlisted an array of big-name singers to lend their vocals to what he envisioned as a death metal version of Carlos Santana's guest-heavy Supernatural. Grohl returned the favor in 2008, performing on Lemmy's cover of Chuck Berry's Christmas classic, "Run Rudolph Run." Lemmy also made a cameo in the Foo Fighters' video for "White Limo," playing the driver who swerves around L.A. while picking up the members of the band.
