PHOTOS: Shiloh Jolie-Pitt Sucks Her Thumb

3-year-old Shiloh Jolie-Pitt is growing up so quickly. She’s outgrowing her clothes and she’s getting bigger by the minute, but there’s one sure sign that she’s still a little girl: her thumb sucking.

Shiloh is on set with mommy Angelina Jolie for The Tourist, which she is shooting in Venice, Italy with Johnny Depp.

Shiloh is not the girlie girl type, instead of dresses, she wears pants and she has a boyish haircut. Daddy Brad Pitt says she doesn’t go anywhere without her security blanket.

And Angelina doesn’t go anywhere without her beautiful children. That’s what makes a superstar mom!
