Holmes, who gave birth to daughter Suri last April, is set to become Mrs. Tom Cruise this fall.
According to Britain’s Sunday Mirror, the star of the film Batman Begins, among others, is revealing to friends that she feels isolated with her baby and Cruise’s family, and isn’t sure that she still wants to wed the Top Gun star.
Holmes, 27, told a source, "I don’t have my own life any more. I’m not comfortable."
The source added, "The wedding dress is bought. Katie is nervous about making a commitment to Tom and the early excitement of their love affair has worn off."
