War Machine Almost Killed Me ... 18 Broken Bones, Ruptured Liver

The woman MMA fighter War Machine allegedly beat to a pulp says she was actually pummeled within an inch of her life.

Porn star Christy Mack says War Machine broke up with her in May but for some reason showed up at her house at 2 AM Friday. She says he walked in, didn't say a word but unleashed a beating on her friend.

War Machine threw the friend out of the house and then she says he allegedly made her strip and shower in front of him. Then she says the beating began ... resulting in 18 broken bones around her eyes, a broken nose, missing teeth, a fractured rib and ruptured liver.

Mack says she ran out of the house naked, begging neighbors to help her. One did and took her to the hospital, where she remains.

War Machine is on the run. There's a $10,000 reward for his capture.
