After Katie Holmes and Tom Cruise gave up on the Oscars ceremony, the public were confused. However, now they know why the couple missed out on such an important event.

It seems that the 30 year old actress was simply too tired, because she has been subject to a rigorous detoxification diet, and is preparing for a second pregnancy, writes Daily Mail.

Katie has for some time now been on a strict diet that is comprised of bio-drinks and a procedure that cleanses the body from harmful toxins.

A source close to the couple told the media that Katie has nearly cleansed her body from toxins, but the strict diet is making her lethargic. Tom is supporting her to keep the diet by hoping that she will soon conceive a second child.

Holmes allegedly blindly keeps to the teachings from the book “Scientology Second Dynamic”, that has strict rules and advice relating to conceiving a child and married life in general.
