Lady Gaga was spotted walking around Rome while on break shooting the upcoming House of Gucci biopic, and of course was repping some metal (as she does). Lady Gaga was wearing a Biohazard Scarred For Life shirt designed by Alan Robert in 1989, or as The Daily Mail refers to it, "graphic print tee."
Of course the shirt has been reprinted and is available here.
Gaga has made no secret over the years of her love of heavy metal. In addition to performing with Metallica at the Grammys a few years ago, she loves Black Sabbath, considers Rob Halford a friend and took out Babymetal on tour. Even James Hetfield has praised her love of metal.
