Jennifer GarnerJennifer GarnerSomeone's had to stay away from Jennifer Garner's ladylumps.

But it ain't who or what you may be imagining.

Chatting about her new action movie, The Kingdom, Jen said: "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."

The movie's directed by Peter Berg, who Jennifer has acted alongside before.

Jen revealed: "Pete Berg was a guest star on Alias the first season, in which he and I had a fight. His idea of doing the fight was to improvise. I am a girl. I don't really want to be punched.

"So I shouldn't have been surprised (about his approach to directing The Kingdom).

On filming The Kingdom's action scenes with one of her co-stars, Jen said: "He just tried to grab me and pull my face off.

"He had a scab on his ear because I bit his ear, and I just went 'Erg!' and yanked. I actually got his ear. Oh, it was nasty. It was great."

But there was one no-go area.

She said: "He had to stay away from my boobs, because I was breastfeeding.

"He could go for my head, pull my hair - just not the boobs."

Crumbs. What did hubby Ben Affleck make of all this?

Jen says: "He was just like 'Go, go for it, babe! Harder!'

What a supportive hubby ol' Ben is.
