Rumors are flying that actress Katie Holmes and husband, actor Tom Cruise, are trying to have another baby.

The couple already has a three-year-old daughter named Suri.

The reason the rumors have started is because in the Scientology religion it is believed to be helpful for the woman to undergo Scientology “auditing” in preparation to have another child. The auditing is used to build self confidence, happiness and spiritual freedom of the mother to in turn make the pregnancy the best it can be for the baby.

Katie was said to have spent four hours at the Scientology Center in Hollywood, California last week – something she did just before announcing her first pregnancy.

A source revealed to the New York Post newspaper: “This is exactly what happened just before she got pregnant with Suri. Tom has made no secret of the fact that he would like another baby.”
