We’ve never been to a Pretty Reckless show, but we’ll be sure to sport our finest lingerie when we finally do. Taylor Momsen, her band and a gaggle of half-naked fans got down last night in Barcelona, and the scene looked like a parent’s worst nightmare. We have to admit when we first saw these pics we dropped our best “I’m a mom and I’m appalled face!” But then we spent a second remembering the things we did at 17 (yes, Taylor is 17) and we quickly backed off. We did dumb stuff. At concerts. In our bra. Expressin’ yourself, and all that teenage jazz. We kinda get where these girls are coming from, but we’re still kinda like “Woah, ladies, chill it on the grinding!” You know?
