Rob Lowe vs. Jessica Simpson

There's a court hearing today in the Rob Lowe nanny lawsuit, and when the judge called the case in the courtroom he must have had some wishful thinking ... he actually said "Rob Lowe vs. Jessica Simpson."

The judge meant to say Jessica Gibson, another Jessica who's looking for a hit.

Now the best part ... before entering court, Jessica and her lawyer, Gloria Allred, posed for pics with the courthouse janitors. Will Gloria also clean up in court today?

Stay tuned ...
