Lindsay Lohan as a stripper?!?

What's next, Stephen Colbert as an American patriot?!?

The actress, in preparation for her role as a topless dancer in I Know Who Killed Me - or just for her next night out - spent nearly three hours at NYC strip club Scores West last night.

According to Page Six, Lohan jumped onstage for an impromptu Perrier-fueled striptease, then made reparations for calling strippers "whores" and "c--ts" in a recent e-mail to friends.

"I love strippers," the actress said as she entered the boobie bar at 12:30 a.m.

"She got up on the stripper pole and began to dance with the Scores Girls with 400 customers cheering her on," a source said. "Then, she joined her entourage of 15 in the VIP area, and got lap dances from many of the girls, including a special double-dance from two strippers at once."

Let's just hope innocent, young Ali Lohan didn't witness her sister's behavior.

Lindsay also went out of her way to pull topless dancers into the bathroom to apologize for her recent, negative comments about the industry.

One of the dancers, Brooke, said all was forgiven. She also added:"She'll make a good stripper - she's a natural."

There's a shock. Naturally, Katie Rees will be available to offer Lohan any tips if necessary.
