Tom Cruise has bought an ultrasound machine for his pregnant actress fiancee Katie Holmes so they can monitor their unborn child at home.
Holmes and Cruise announced their engagement in June
The Jerry Maguire star said the device - which costs up to $200,000 (£116,000) - would be donated to a hospital when they have finished with it.
But he told US network ABC he did not yet know the child's gender.
Cruise, who announced his engagement in June, said the couple will tie the knot in summer or early autumn next year.
In October, Cruise and Dawson's Creek star Holmes, 26, said they were expecting their first child together.
Cruise, who has been married twice before, has two other children - Connor, 10, and Isabella, 12, whom he adopted with previous wife, actress Nicole Kidman.
Cruise said the couple will do their own scans with the ultrasound machine which show fetus development.
But he said he would not reveal whether the child was a boy or girl to the media ahead of the birth.
When presenter Barbara Walters asked him, "So what do you see?", the 43-year-old actor said "A little baby".
Cruise is currently in Shanghai, China to film scenes for Mission Impossible 3.
Excerpts from the interview, which will be broadcast on 29 November in a show about the "most fascinating people of 2005", have been published in People Magazine.
