Jessica Jaymes and Nick Lachey

Pity the poor Simpson sisters: first Ashlee's gastrointestinal-related lipsynching fiasco on "SNL" last weekend causes her to become the subject of a million punchlines the world over, and now we read that Nick Lachey has allegedly been caught canoodling with busty porn babe Jessica Jaymes, star of "Assfixiation" and "If These Hips Could Talk". (Fascinatingly enough, "Splitsville" is one of Ms. Jaymes' titles too.)
