We hope you are sitting! Just when we thought the stars were done with the head to toe black look, the rug has been pulled out from under us!

Kristen Stewart, Ashley Olsen, and Monica Cruz are all back to the Ninja chic look. Kristen Stewart was seen outside a taping of the David Letterman show last night in her Ninja Garb.

Ashley Olsen and Monica Cruz both showed up to the Mango Store in Soho in their Ninja Costumes as well. Uh- oh....we better be nice before they fall from the ceiling and kick our Ninja hating...well you get the point.
