The Zell was on the set of her new flick My One and Only in Marina Del Rey, California, when she got a bit snap-happy.

But what could have piqued Renée's curiosity? Did she spot a myna bird pecking at a small child in a stroller on the sidewalk?

Maybe she saw Lindsay Lohan and Samantha Ronson off in the distance shucking oysters. Mmmm. Brine.

Or did camera-shy Michelle Williams make a rare undocumented appearance and wheel her kid by the set?

Whatever it was will stay a secret. Renée is a myterious labyrinth that the world will never understand.
