Despite the fact that Shailene Woodley goes completely nude and seduces a 45-year-old man in her new film "White Bird in a Blizzard," it's still teen blockbusters like "Divergent" and last summer's sleeper hit "The Fault in Our Stars" that have made the actress a household name.

However, according to Woodley herself, that youthful, girl-next-door identity is about the change -- largely due to her own reaction to watching "Fault."

"We filmed it in August, and I saw the rough cut in December," she told MTV News. "I started crying, and it wasn't because of the movie... it was because I realized -- and it hit me so hard -- I was like, 'Wow, this is such a bittersweet, beautiful moment, because Fault is the last movie I will ever play a teenager in.'"

Now of course, Woodley's frequently makeup-free, youthful face could definitely still land her another "Fault"-esque role, but it isn't the cruel process of physical aging that's keeping her away from high school hallways.

"I can't empathize with the process that a teenager mentally and emotionally goes through now like I could even last August, just simply from my own phases and my own personal life," she continued. "It was a really neat, amazing moment, and also a totally terrifying moment of like, 'Wow, I have to be held accountable for playing my own age for the first time.'"

This also rules Woodley out for a plethora of YA blockbuster franchises -- or any blockbuster franchises, for that matter. (Sorry, Marvel?)

"I cannot imagine doing another big movie right now.. I can't imagine doing more than one," she concluded. "For me, I'll never just work to work. It has to be about the butterflies that I either get, or I don't get. It's not often that you get butterflies."
