Lohan suffers for her art

Lindsay Lohan faces an uncomfortable movie shoot after preparations for her latest role as a pole dancer left her covered in bruises.

The actress has been taking striptease lessons from a professional ahead of filming I Know Who Killed Me, but is now regretting the hands-on research.

In an email sent to friends Lohan moans: "So… three hours of pole dancing and bruised everywhere… I mean we're talkin' like a walking black-and-blue mark."

Lohan's spokeswoman Leslie Sloane Zelnik confirms to PageSix.com: "She's been in rehearsals for the film and has been taking classes.

"Her character is a stripper, and she now realises that the job isn't easy. We should give these women credit."

Lohan faces another five weeks of discomfort while she completes the movie.
