Katie Holmes and Tom Cruise "joyously welcomed the arrival of a baby girl, Suri, today," Cruise's rep said in a statement after PEOPLE first broke the news Tuesday afternoon. "The child weighed 7 pounds, 7 ounces and was 20 inches in length. Both mother and daughter are doing well." The name Suri has its origins in Hebrew meaning "princess," or in Persian meaning "red rose," the rep added.

In October, barely six months into their romance, an ecstatic Cruise and Holmes revealed that they were expectant parents. Cruise, 43, and Holmes, 27, had made no secret of their desire to start a family together: When asked by PEOPLE last June if they were planning to have children, Holmes smiled and said simply, "Yes."

Friends of the Toledo, Ohio-bred Holmes called her perfectly suited to her upcoming role. "She almost seems born for motherhood," said Oliver Hudson, actress Kate Hudson's brother and an old pal who costarred with Holmes in Dawson's Creek. "She's a nurturer. She's got mother qualities a lot of girls her age don't have." Cruise, meanwhile, is "a great dad already," according to his pal, actress Leah Remini. He has two children from his marriage to Nicole Kidman: Isabella, 13, and Connor, 11, whom Cruise and Kidman adopted as infants. Remini told PEOPLE that both kids are "so cool…You can sit and talk to them about life."
