It's a baby girl for "Titanic" star Kate Winslet, 25, and her husband of two years, movie director James Threapleton, 26. Mother and daughter -- who weighed 8 pounds, 9 ounces when she arrived on Thursday -- are due to go home from the hospital in London today. "Kate and Jim had drawn up a list of 10 names, but when the baby was born none of them seemed right," Winslet's New York agent Robert Garlock told the Associated Press. "Then Mia came to them, and it seemed just right." Winslet spent the summer filming the British movie "Enigma," a drama about breaking the code during World War II. She now reportedly intends to take a seven-month break to be with Mia in the Threapleton's $1.17 million riverside home in southern England.
