NEW YORK — Katie Holmes and Tom Cruise are expecting a baby.

Holmes' pregnancy was reported yesterday by People magazine. The two became engaged in June.

"Tom and Katie are very excited, and the entire family is very excited," Lee Anne DeVette, Cruise's spokeswoman, told People.

It would be Holmes' first child. No wedding date for the couple has been set and no details about the gender of the baby or the due date were available.

Cruise adopted two children, Connor, 10, and Isabella, 12, during his marriage to actress Nicole Kidman. That marriage ended in 2001.

Twice-married Cruise, 43, and Holmes, 26, began dating in mid-April but far from keeping their relationship low-key, Cruise became the butt of jokes in May after he jumped around on a couch in a manic appearance on "The Oprah Winfrey Show" and declared his passion for his new girlfriend.

He proposed to Holmes in June at the Eiffel Tower in Paris and announced their engagement the next day at a news conference.

The high jinks prompted suspicion that their relationship was a publicity stunt to promote their summer films: "War of the Worlds" for Cruise and "Batman Begins" for Holmes.

Holmes made her name on the TV show "Dawson's Creek." She ended a five-year relationship with "American Pie" actor Chris Klein in early 2005.

Cruise's first marriage, to actress Mimi Rogers, ended in divorce in 1990. After his divorce from Kidman, he had a two-year relationship with Spanish actress Penélope Cruz.
