JEN ANISTON TRAUMATIZED

Jen Aniston's most horrid nightmare come true!

No, not Gerard Butler groping her on the red carpet …

Hyping new flick Bounty Hunter Aniston revealed the terror of her experience about being locked  away in the trunk of a car.

"They left me in that trunk once," she revealed to David Letterman

"They were like, 'Are you going to be OK? We're going to shut you in the trunk?'

"And I said it was fine, and every couple of takes they'd open the door and give me a sip of water and a cracker. 

"And there was this one moment where they were overly discussing a shot and all of a sudden all the voices faded and they'd gone over to the monitors - there's one camera in the trunk, I don't know what they were looking at but I had a little panic."
