Katie Goes To Scientology Boot Camp?

Could there be trouble in Xenudise? The Star is reporting that, at Tom Cruise's insistence, Katie Holmes recently spent a few days in the desert at a compound for hardcore Scientologists!

The mag alleges that Katie spent three days in Hemet, California at Gold Base, a "remote, supersecret Scientology compound", where she underwent rigorous auditing sessions and intensive purification processes. The Star even claims that some sessions went as long as 36 hours straight - with little in the way of food or sleep!

"It included various tests, confession sessions, tons of reading and physically challenging purification processes," a Scientology insider revealed to the Star. "Tom insists that auditing and purification practices are incredibly beneficial to Scientologists at all levels."

Calls to Holmes' rep for a comment on the Star's report were not immediately returned.

Hopefully this news doesn't turn out to be true - I mean, 36 straight hours of auditing?
