Why Taylor Momsen Is "Forever Grateful" Jenny Humphrey Left 'Gossip Girl'

While viewers might have been shocked at Jenny's transformation (I was, at least), taylor-ing Jenny's look, and moving from feminine to edgy, actually helped Taylor through the difficulties of filming Gossip Girl. Articles at the time claimed Taylor was "unprofessional," and being the youngest member on the GG set (Taylor was 12 when they filmed the pilot, Penn was 20) was incredibly difficult — especially since it was such a public filming process.

"It was weird for me suddenly overnight being tabloid famous, which is a different kind of famous," she says. "They would photograph me on set [on the streets of New York City]...as my character and put it in the tabloids as 'Taylor Momsen'...and that started to really bug me because my identity was getting kind of taken over...People had this perception of me that wasn't me and I became really hyper-aware of how I carried myself."

"As I was growing and changing, they wanted the character to reflect that, too," she continues. "At the time, I was sitting there going, 'Well, at least I don't hate this outfit.'"

Taylor started her rock band The Pretty Reckless in 2009 (they're still together today), and while fans might have viewed her as an actress-turned-singer, she always cared more about music than anything else. When she got old enough to realize that she could control her life, she made an almost-immediate 180.

“It was like a click," Taylor says. "I woke up one morning and went, ‘Wait a second. I don’t have to do this? I don’t have to do this other job? I can just play in my band and tour and write songs?’"

Even though it was more a little bit more complicated to leave a hit TV show than just not show up to work, she was able to stop working on Gossip Girl. Jenny leaves Manhattan for London in season 4, and doesn't return until the final scene of the series finale.

“They went, ‘Well, we can’t let you out of your deal, but we can write you out of the show, so you can go on tour,'” she continues. “They really allowed me to follow my dream, and I’m forever grateful and thankful to them for that.”
