The 'Alias' star - who was breastfeeding daughter Violet at the time of filming - revealed she got beaten up for real on the set of 'The Kingdom', but her breasts were off limits.
Jennifer told People magazine: "It was so down and dirty that I had scratch marks that we had to cover up on my face for the next few days.
"But the guy I was fighting had to stay away from my boobs because I was breastfeeding. That was the one sacred thing. He could go for my head, pull my hair, just not the boobs.
"I gave as good as I got, I even bit his ear. It was great!"
The '13 Going On 30' star also revealed her husband Ben Affleck was not at all concerned when he came to the set to watch her in the violent fight scenes.
She said: "He was just like 'Go, go for it, babe! Harder!' I thought it would have made him a little bit nervous to see people chucking me against the wall, harder and harder with every take."
Jennifer plays a US government agent in action film 'The Kingdom' which is set in Saudi Arabia, though it was filmed in the Arizona desert.
The action star recently revealed she collapsed on set in the desert temperatures which reached 140 degrees Fahrenheit.
She said: "I succumbed to the heat a couple times. I was still breastfeeding my baby and everything your body needs, all the electrolytes goes to the baby, and so my system was all screwed up and I got heat stroke twice.
"They gave me an I.V. and sent me back out!"
'The Kingdom' stars Jamie Foxx, Chris Cooper and Jason Bateman.
