Elise from Reign In Blonde pointed this pic of Ke$ha in a Metallica shirt out to us on Twitter (you’re following RiB on Twitter, right?). On the one hand, she’s been on camera talking about metal in the past, but it’s not like she really acquitted herself. She liked Slayer, Protest the Hero and Devildriver, but really dug Steel Panther, so if anything she’s proven herself a hair metal fan. And Metallica is a band that’s mainstream enough that everyone knows who they are, but is still edgy for the typical Ke$ha fan. At the end of the day, I’d be willing to give her a pass, but only if she could name three songs off …And Justice For All, the album she’s wearing the T-shirt for.
