How Can You Not Get Modeling Jobs

Gabriel Aubry is fighting Halle Berry's attempt to slash his child support by more than 75% ... because her husband beat the crap out of him so bad he can't get work, but the photos tell a different story.

TMZ has obtained documents filed in their never-ending custody and support war. We broke the story ... Halle is trying to reduce Gabriel's child support for 6-year-old Nahla from $16K a month to around $3,800 a month.

Gabriel refers to the Thanksgiving day fight in Halle's driveway back in 2012, in which he accuses Olivier Martinez of a sneak attack that pulverized his face. He says it took him 6 months to heal before he could possibly work again, and since then he's only gotten 3 gigs.

But we checked out photos of Gabriel, and just 6 weeks after the fight there's barely a sign of injury.

Halle attacks Gabriel as a deadbeat who is using child support to avoid having to work. She says, "There is no case, no law, no logic that says a healthy, active man gets to simply live off child support that the wealthier mother earns."

And in Halle's docs, her lawyer, Steve Kolodny, says Gabriel uses monthly child support for his own needs, including:

$740 a month for Gabriel's "Fitness"

$940 a month in clothing (Gabriel lists Nahla's clothing expenses separately -- $675 a month)

$700 a month for Gabriel's health insurance

$1,975 a month in car expenses

$1,100 a month in furniture and electronics
