Raising six kids alone is absolutely not easy, and Angelina Jolie arguably knows the struggle better than anyone else. The "Maleficent" actress reportedly is having a hard time disciplining her kids, Maddox, Pax, Zahara, Shiloh and twins Knox and Vivienne, without ex-husband Brad Pitt.

Things post-divorce are becoming trickier and chaotic for the "Mr. and Mrs. Smith" actress, especially in parenting department. When Angelina and her kids moved into their new mansion in Los Angeles, she promised them that "they could all decorate their rooms."

However, it may be not the best decision to make as it only leads to trashed rooms. "[It's] a cross between a trashed frat house and a DayGlo-covered rave club," says a source to In Touch Weekly. The kids reportedly "express themselves by scribbling and coloring on the walls." The source goes on saying that "Angelina has lost control. It's shocking what goes on in this house."

"It's a house of horrors," the source adds. "Food and water fights and soccer games in the house remain the norm. Angelina has no clue what she is doing. There are absolutely no rules."

Further making everything worst, there are also no curfews for the kids. "It's not uncommon for all of the kids to be up past midnight during the week, eating sugary snacks and soda," a Brad source claims. "They go to bed very, very late and end up sleeping in very late the next day."

In addition, they let loose their collection of pets on visitors and household staff as the source reveals, "The kids delight in letting loose their collection of animals--a number of dogs, cats, hamsters, snakes." The source continues, "The kids have been very openly defiant and unmanageable when it comes to tutors and nannies."

The chaos is seemingly too overwhelming to the point it's not only happening behind closed doors. Just recently, Shiloh and Vivienne were spotted walking barefoot through a Target parking lot.

It seems like Angelina needs more time to adjust her life as a single mom after divorcing from the "Allied" actor. "Although she's maternal, as much as she wants to be, Angie's not good at being a homemaker," says an Angelina insider. "Juggling basic caregiving and daily schedules that include playdates, doctor's appointments, and organizing meal times for her brood is all too much to her."
