One intrepid reader found Madonna at S Fifth St. and Marcy Ave. in Williamsburg, Brooklyn today shooting scenes for her upcoming movie W.E.. He even filmed a video of her! Our Stalker game has officially been stepped up.

The footage is below. She's the one in the hat getting into the car and leaving the set this afternoon. It's not amazing, but it's still a stalker movie. You have a sighting, celebrity photo, or a video to share with us? Either email us or post it to #stalker yourself.

[There was a video here]
