Julia Stiles is expecting her first child with fiance Preston Cook.
Stiles representative Annick Muller confirmed the pregnancy to The Associated Press on Tuesday but didn't offer any word on a due date.
The 36-year-old actress is in London promoting her new TV show, "Riviera." The host of a London radio show tweeted a picture of Stiles cradling her belly on Monday.
