Actress Katie Holmes has already missed some big events like the Oscars and New York Fashion Week due to an extreme detox in efforts to have a second child with husband Tom Cruise.   

That was about a week ago, and now Katie is looking thin and washed out according to some people on set of her new movie, The Extra Man.  Peejay Bodoy, the restaurant manager of where the movie is being filmed, told Life&Style,

"I was shocked at how skinny she was."

"During the entire time she was here, I did not see her eat anything -- not a morsel. After five or so hours, I would have been famished!"

Katie is not hiding the fact she's on a diet neither, she tells Life&Style,

"As you can see," Katie said, holding up a drink, "I'm on my liquid diet right now."

Scientology researcher Rick Ross also suspects it's at the urging of her husband, Tom Cruise, a longtime devotee of Scientology and one of its most powerful leaders.

"Tom may be telling her it's good for her, that there's some reason she needs to be doing it," Ross tells Life & Style.
