Actress Katie Holmes has changed more than just her religion since she started dating Tom Cruise last year (05) - she's now altered her first name. Despite her strict Catholic upbringing, the former DAWSON'S CREEK beauty converted to Scientology when she began her relationship with the Top Gun heart-throb, and will bring up their baby daughter SURI in the controversial religion. After discussing the issue with Cruise, Holmes has decided her Christian name 'Katie' sounds too young for a 27-year-old and is now known to friends and family as 'Kate'. Cruise explains, "Katie is a young girl's name. "Her name is Kate now she's a child-bearing woman."
