Karen O was in Cleveland last night to attend the 30th annual Rock and Roll Hall of Fame induction ceremony, showing off a badass all-black ensemble that included a studded leather jacket and a surprising baby bump. Along with Patti Smith and Beck, the singer was on hand to honor two-time inductee Lou Reed. O also got on stage to perform Lou Reed’s “Vicious” with Yeah Yeah Yeahs bandmate Nick Zinner.
