In an interview with Blackbook magazine, Kate says:

    "The panic you see flooding me in that rape scene is real. I told Alex not to worry about me, to just go for it."

In the scene, Skarsgard's aggressive farmhand character, Charlie, rapes Bosworth's character, Amy.

Kate adds:

    "And it was actually violent. He's a huge guy. When he was ripping off my clothes in front of a room filled with men, even though I knew it was make-believe, it was still incredibly violating and terrifying."

Once filming wrapped, the two began dating in real life, but recently split.

We caught up with Kate as she shopped on Melrose on Wednesday -- see the pics below!
