JAMIE LEE CURTIS - CURTIS IN PAIN AS ALLEN POKES HIS FACE WITH A FORK

JAMIE LEE CURTIS had to go to extremes to stop herself from laughing and ruining hilarious scenes in her new comedy film CHRISTMAS WITH THE KRANKS - she pinched a toothpick.

The actress couldn't stop herself from giggling in one restaurant scene, where she had to sit across from co-star TIM ALLEN as he poked his Botoxed face with a fork, so she opted for pain instead.

She says, "I literally take something sharp, like a toothpick, and I squeeze it as hard as I can between my fingers and hold it below the camera as I'm looking at this guy with this rubber face sticking a fork in his face.

"I'm squeezing it until I am bleeding. I do that so that my mind goes to the pain and not to laughing at his face."
