Brad Pitt and Angelina Jolie have six children, three boys and three girls, but recently, the soon-to-be-divorced couple seems to have not three, but four boys on their hands.

In family photos throughout this year, Shiloh Jolie-Pitt, the oldest biological child of Pitt and Jolie, has been seen with short hair, baggy clothing, including t-shirts and shorts, and baseball caps. However, Shiloh isn't a boy. She's a girl.

“Shiloh’s so funny about her wardrobe and she couldn’t be more different from her sisters,” an insider recently revealed to OK! Magazine. “She only wears boys’ clothes and is always stealing T-shirts from Pax’s wardrobe.”

In 2010, as the Inquisitr revealed, Jolie explained to Vanity Fair that her daughter Shiloh “wants to be a boy."

“We had to cut her hair,” Jolie said. “She likes to wear boys’ everything. She thinks she’s one of the brothers.”

Angelina and her husband are “being extremely responsible about her tomboy ways,” added the magazine's source. “[They are] committed to giving Shiloh a loving family environment.”

“Angie and Brad are getting advice from all kinds of experts on how to handle it carefully and not damage their child,” noted the insider. “They are worried she might get bullied, but she’s a tough little nut who totally knows her own mind. She’s a very impressive young person with a killer brain on her shoulders.”
