Katie Holmes is reportedly having doubts about marrying Tom Cruise.Then 'Batman Begins' star gave birth to fiancé Tom's daughter Suri in April and the pair planned to tie the knot this autumn.However, Katie allegedly told a visitor to the isolated Colorado retreat where she has been staying with Suri and Tom's family that she is unsure about making a "commitment" to the 'Top Gun' actor.According to Britain's Sunday Mirror newspaper, she told the visitor: "I don't have my own life any more. I'm not comfortable."A source added: "The wedding dress is bought. Tom's two adopted kids from his marriage to Nicole Kidman will be there, but just where and when is up in the air. Katie is nervous about making a commitment to Tom and the early excitement of their love affair has worn off."Katie is apparently worried that being Tom's partner and the mother of his child has got in the way of her own film career. The actor is said to have any film scripts his fiancée is considering read by advisors from the Church of Scientology - of which he is a prominent member - for their approval.
Despite Katie's apparent concerns, Tom, 44, has told family and friends to be "prepared and ready" for a wedding any time soon.
The nuptials are reportedly set to take place either at the Scientology Celebrity Centre, in Los Angeles or at their home.
