Holmes 'preparing to get pregnant'

Katie Holmes has sparked speculation she is preparing to get pregnant.

The Hollywood actress already has three-year-old daughter Suri with her husband Tom Cruise.

The pair have been open about their desire to expand their family at some point, and Katie has now been seen spending increased amounts of time at the Hollywood Scientology Center.

Both Katie and Tom are scientologists, with Katie spending more time than usual at the centre before she fell pregnant last time.
