Taylor Momsen is once again pushing boundaries and turning it all the way up for a new music video, stripping down to her birthday suit and wearing only black body paint. The musician, widely known as Gossip Girl's rebellious Jenny Humphrey, embraced her dark side for the shoot with her band, The Pretty Reckless. "Go behind the scenes with us on the making of the 'For I Am Death' music video. Out Friday," she captioned a series of photos shared via Instagram on Wednesday, September 3.
