Ben and Jen Affleck are having a Girl!

Ben Affleck and Jennifer Garner are reportedly expecting a baby girl. A source claims the couple let slip the secret of their unborn baby's sex while in the Turks and Caicos Islands, where they recently married. According to America's In Touch magazine, Ben was overheard saying to his new wife at the low key wedding: "My mom wants to know what we're going to name her, but I say, 'What does it matter what she's named if she has a healthy granddaughter?' "Our baby will be perfect. " The smitten couple, who met on the set of movie 'Daredevil', tied the knot at the end of last month on a beach at sunset. Following the surprise wedding - which was attended by family and close friends, including Jennifer's 'Alias' co-star Victor Garber - Ben and Jennifer spent their wedding night in a £100-a-night beachside villa on the tropical island of Parrot Cay. The couple got engaged in April but tried to keep their wedding plans secret because Ben did not want a repeat of the media frenzy that surrounded his doomed engagement to Jennifer Lopez. Shortly after he started dating Garner, Ben said: "I'm certainly not going to talk about who I am or am not dating.
