Hollywood actor Tom Cruise can't wait for his fiancee Katie Holmes to give birth to their baby, because he is so excited at the prospect of changing nappies.

The WAR OF THE WORLDS star, who will marry 26-year-old Holmes after their child is born next year (06), wants to show his commitment to his new family by being a hands-on father.

He says, "It's exciting, changing diapers, being there and having that whole experience. I can't wait."
