While you ate lunch, celebrities roamed the Earth. Today in #stalker sightings: Jude Law and Sienna Miller (twice!) and John Slattery.

There are two new ways to submit sightings: 1. You can email them to stalker@gawker.com or 2. see your sighting published immediately on the site (if you're an approved commenter) by using the Share box at the top of the front page and including the #stalker hashtag. Either way, be sure to give us details you'd want to know - what they were wearing, what they said, who they were with, what they ate. Brownie points for spelling their names right and using proper capitalization.
