Shiloh Jolie-Pitt, 3, sported a skull cap and toy gun holster as she got into a water taxi in Venice, Italy, with parents Angelina Jolie and Brad Pitt over the weekend.

A source tells Shiloh picks out most of duds and accessories, which have included a toy sword. (See more photos of the Pitt-Jolie brood in Venice at!)

Though her tomboy style has turned heads, experts say Jolie, 34, and Pitt, 46, have nothing to worry about. "It's quite healthy, as she is learning to make choices and think independently," says Manhattan psychotherapist Jonathan Alpert, who writes a column in Metro newspaper called "No More Drama."

Shiloh isn't the only Jolie-Pitt child to have an interest in weapons.

In the November 2008 issue W magazine, Jolie - who was involved in self-mutilation when she was still a teenager - said she bought her then-7-year-old son Maddox knives.

"My mom took me to buy my first daggers when I was 11 or 12," Jolie said. "And I've already bought Maddox some."
