We all knew Jennifer Lawrence starred in the Hunger Games, but we didn’t know they drove her mad in real life as she makes a shocking confession.

The 27-year-old actress thinks about "pushing people on the tracks" when she rides the subway

and she made this bizarre confession while taking a lie detector test for Vanity Fair magazine.

The ‘Joy’ star was forced to make a decision over redirecting a speeding train so that it only hit one person,

or leave it and allow it to plough into a group of 20 people.

Although Jennifer would save the 20 people, she admitted that she's thought of pushing a person in front of the train

- even though she'd never actually do it.

Although this confession is weird, we still love you Jennifer, even though this statement is a bit of a train wreck...
