Brad Pitt and Angelina Jolie‘s ongoing divorce has been a mess, and someone, in particular, isn’t handling it well. And that someone is their daughter Shiloh, 12. According to Star, out of the former duo’s six kids, she’s taking her parents’ split the hardest.

“She’s the most sensitive of all the kids, and she’s definitely the most upset by the divorce,” a family friend revealed to the magazine in its latest issue, on newsstands now. “It’s been two years and she is still struggling: it’s been one upheaval after another. Brad and Angie say they want what’s best for the kids, but they’re both too stubborn to let the small things go.”

Brad, 54, and Angelina, 43, previously married in 2014 and announced their split in September 2016. In addition to Shiloh, they are parents to five other kids: Maddox, 17, Pax, 14, Zahara, 13, and twins Knox and Vivienne, 10. 

According to the insider, Shiloh hasn’t been treating her brothers and sisters well throughout their mom and dad’s breakup. “Just a couple of months ago, Shiloh ran away from home and was gone for hours before anyone even realized it,” a friend revealed. “And when she is home, she gets into fights with her brothers and just pummels them! Shiloh is taking out her frustration on her siblings. She’s a tough girl and is acting out.”

But her siblings aren’t the only ones she’s outing. The soon-to-be teenager is allegedly ignoring her father as well. “She acts like she hates him sometimes,” a friend shared. “She will refuse to talk to Brad when he calls.”

We’re just hoping Brad and Angie work it out before things get even worse for Shiloh and the rest of their brood. “The kids are still going to therapy, and that’s a good thing. If Brad and Angie don’t nip their damaging behavior in the bud, Shiloh could be destroyed for life.” What a mess…
