Kristen Stewart Says 'Twilight' Made Her Who She Is

— -- Playing Bella Swan in "Twilight" catapulted Kristen Stewart to A-list fame.

It also changed her as a person.

"It was something really personal for a couple of years," she told E! News. "It was part of who I am."

Stewart, 24, starred in all five "Twilight" films, and famously dated her co-star Robert Pattinson for years. So, when asked to reflect on the experience, it was hard for her to express just how much the franchise meant to her.

"It was five years of my life. I don't know how to button it up and say what I gained, it was just, I was able to work for years and years on something that took so much out of all of us and did not leave us empty. [It] replaced every bit that it took," she explained. "Obviously, on an exceptionally obvious note, it's opened a lot of doors, but I've become who I am because of that."
