If you're claustrophobic then stop reading now as what happened to Jennifer Aniston on set of her new film, The Bounty Hunter, will freak you reet out!

The gorgeous actress appeared on the Late Show with David Letterman and revealed how she “had a little panic” when she was left locked in the boot of a car on set.

Jen was scared as she was left in the trunk whilst the crew walked off to discuss a scene...

She told David: "They left me in that trunk once. They were like, 'Are you going to be okay? We're going to shut you in the trunk?'

"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."

Sounds far too scary for us, we would have had a full on freak out! You wouldn't find other Hollywood actresses prepared to stay locked in the boot of a car for more than a few minutes. Good ol' Jen!

At least Jen had Gerard Butler to comfort her afterwards...
