Reportedly, Patrick Aufdenkamp isn't just a bad influence on kindergarten students learning to spell.

Those close to Lindsay Lohan claim this old friend is endangering her sobriety, often putting the Firecrotch Queen in situations that involve alcohol and drugs.

TMZ reports that Aufdenkamp is somehow not sleeping with Lohan, but he may be putting the progress she's made in serious jeopardy.

"He has nothing to offer her," a source said, "and he looks at Lindsay as his meal ticket."

Patrick Aufdenkamp: Weird name, dangerous companion of Lindsay Lohan.

Lindsay's rep had no comment on the matter, but Lohan has supposedly been warned numerous times about Patrick Aufdenkamp. But she was probably too busy straddling random Italian dudes to listen.
