Matt Damon's wife Luciana Barrosa has given birth to a daughter Stella. This is the third child the couple has had together, all girls, and Ms. Barrosa also has a daughter from a previous marriage.
It may not be quite correct to say the tabloids were scooped on this. While Matt Damon clearly counts as a movie star, the supermarket rags leave him completely alone, probably because he's happily married and his wife isn't famous.
