Pregnant Reese Witherspoon Shows Off Her Growing Baby Bump (PHOTO)

Reese Witherspoon may be keeping quiet about her pregnancy, but it's definitely hard to miss her growing baby bump.

The actress landed at LAX in Los Angeles on July 19, and she tried to go incognito, wearing a baseball cap and sunglasses.

Witherspoon has been busy filming her new movie, "Devil's Knot," in Atlanta, and it doesn't seem like her work is slowing down anytime soon. It was announced last week that Witherspoon has signed on to produce the film adaptation of Gillian Fynn's New York Times best-selling novel, "Gone Girl."

But Witherspoon wasn't the only celebrity mom-to-be spotted traveling recently. "True Blood" star Anna Paquin, who is expecting twins, was photographed arriving at London's Heathrow airport on Thursday as well.
