Keke Palmer, 27, showed off her sense of humor when taking on the popular silhouette challenge on Jan. 31! The actress starts off like everyone else in the video, which she posted to Instagram, and brushes her teeth while wearing a light and dark orange tie-dye night shirt. She then walks away from the camera into the doorway of the bathroom before the lights go out and she puts her hands up in the door frame while swinging her head back as she looks to be wearing next to nothing.
