Angelina Jolie's kids love to play with fake blood

Actress Angelina Jolie's kids loved to play with fake blood on the set of her new film.

Jolie admitted that her children - including Maddox, eight, Pax, six, Zahara, five and Shiloh, four, enjoy playing with fake blood.

The 35 year old told UsMagazine.com at the London premiere of her action-thriller Salt: "I would bring them in early in the mornings...and I'd let them [use] blood.

"So we play together, they try on my wigs, they play with the blood."

She added: "They know it is all silly! They test the harnesses and we have them flying around, they know what it is."

The Hollywood star added that just her twins Vivienne and Knox, two, were in London with her on the big night.

Angelina added: "I'm having some special baby time."

The Academy Award winner also gave an insight into her and Brad Pitt's parenting skills.

She said: "We're very much a united front, they can't get mummy to do something daddy wouldn't.

"We're very much the same but we take turns working and we bring the kids to each other's sets, so we try to stay together."
