When metal gods Metallica stepped into a car for Apple Music’s Carpool Karaoke, no one expected what came next. Known for face-melting riffs and thunderous drums, James Hetfield, Lars Ulrich, Kirk Hammett, and Robert Trujillo traded headbanging for harmonizing—and took on Rihanna’s hit “Diamonds.”
Yes, you read that right.

Alongside comedian and actor Billy Eichner, Metallica let loose with an unexpectedly fabulous rendition of Rihanna’s chart-topping pop anthem. As the iconic shine bright like a diamond chorus blared through the speakers, Hetfield and Ulrich joined in with full commitment—head bobs, jazz hands, and all. Hammett even threw in a falsetto that had Billy Eichner dramatically gasping from the front seat.

Originally a fan-favorite segment from The Late Late Show with James Corden, Carpool Karaoke got the full Apple Music treatment with its own spin-off series—and this crossover moment between metal and mainstream pop is one of the most talked-about episodes yet.
What made it magic? The contrast. Seeing the kings of heavy metal belt out a sparkling pop ballad in perfect comedic timing reminds us all: music should be fun, fearless, and unafraid to surprise.

Whether you’re a Metallica diehard, a Rihanna fan, or just here for the chaos—this karaoke moment is pure gold. Watch it, laugh, and maybe even sing along… because apparently, even metal legends shine bright like a diamond. 💎🤘
