What was Katie Holmes thinking?

I wonder if the vibrator is comforting Katie or the foetus, and what it looks like.

Actress Katie Holmes was reportedly thrown out of a California cinema when a vibrating gadget she was holding disturbed fellow moviegoers.

The fiancée of actor Tom Crusie was holding a buzzing aid against her pregnant stomach, as she believes it is comforting to the foetus.

But it failed to soothe the nerves of audience members, who quickly tired of the humming device.

A witness says, "People didn't care that she was a star, they just wanted to see the movie." (source)
