Angelina Jolie getting her 'baby fix' on next film's set

Los Angeles: Hollywood star Angelina Jolie Pitt's kids are all grown up and the actress is getting her 'baby fix' on the sets of her next film "First They Killed My Father".

The 41-year-old actress, who is working on film in Cambodia, was filming scenes that required hundreds of children, reported People magazine.

"I'm surrounded by toys. We have 250 children in a scene, so I filled the house, my car, my trailer with toys. It's my 'I love babies' fix," she said.

"They have to go through a labour camp.They have to cry and scream. My instinct is to want to cut and hug everyone."

"First They Killed My Father" is about the Khmer Rouge genocide.

The actress-director has six children with her husband Brad Pitt ? Maddox, 14, Pax, 12, Zahara, 10, Shiloh, 9, and twins Knox and Vivienne, 7.

Pax, the second oldest, has even started working on her sets, Jolie said.
