It looks like the Brangelina woes are just not ending. The parents of Maddox, 15, and Pax, 12, might simply materialise out of nowhere, giving a "horrific twist" to the Brangelina custody battle.

The nightmare will begin after today, November 30. Pax Jolie-Pitt's birth mother will be released from prison in a short while. The biological parents of Maddox Jolie-Pitt too are thought to be alive, while earlier it was believed that he was an orphan.

"I'm sure both [Brad Pitt] and Angie are freaking out over this. It's been a fear from day one that the biological parents of their adopted kids would resurface," an insider said. 

Their third adopted child is their daughter Zahara, 11, who was brought from Ethiopia.

Maddox was the first child adopted from Cambodia. It was thought that he was an orphan. But now it emerges that it had just been a deal brokered by a crooked agent called Lauryn Galindo, who had been sold Maddox by his mother for just $100. Galindo was imprisoned for money laundering that involved more than 800 babies.

"I'm sure this child was not a real orphan and was not abandoned," said Dr. Kek Galabru of the human rights agency Licadho.

Pax was another three-year-old that had been picked up from a Vietnamese orphanage a decade ago.  Today, his mother, Pham Thu Dung, has asked for him again.

"Most of the normal children are kids of prisoners," Nguyen Kim Xuyen explained to Radar Online. After the parents are freed, they rarely fail to ask for their children. "There are some cases where economic conditions mean they are not able to raise the child [when they're released], so they leave them here, but it's very seldom."

Currently, the situation is pretty terrifying for the Brangelina couple.

"All they know about Pax is that he came to the orphanage at 2 days old after his mother, Pham, ran away from the hospital. With Maddox, they had to rely on Galindo's word."

If Pax's mother comes forward to ask for her child, Maddox's parents would come forward too.

"If Pham makes a bid to win Pax back - and everyone expects she will - it could lead Maddox's parents to come forward," the source alleged. "Taking a child from a parent with no apparent say in the matter won't look good for Jolie's UN status... No doubt Angie'll be praying this can all be fixed with a blank check, but the trauma of possibly losing any of their children is both Angie and [Brad Pitt's worst nightmare come true."

There are more parents involved in battling for the children than just the Brangelina couple. Will the nightmare ever see a dawn?
