American actress Evan Rachel Wood says she couldn't stay silent any longer after revealing she's been raped twice.

The Westworld star posted an open letter on Twitter saying she was attacked by a "significant other" and on a separate occasion by the owner of a bar.

She also says that while she's alive, happy and strong she is 'still not ok'.

Well, since everything is out in the open now, figured I would share the confession letter I wrote to @RollingStone in its entirety. #NotOk pic.twitter.com/0FSP1gsE36
