Divergent star Shailene Woodley has hit out at the Twilight series saying it's "about a very unhealthy, toxic relationship."

The 22-year-old star told Teen Vogue, "Twilight, I'm sorry, is about a very unhealthy, toxic relationship. She falls in love with this guy and the second he leaves her, her life is over and she's going to kill herself.

"What message are we sending to young people? That is not going to help this world evolve."
