Gabriel Aubry vs. Halle Berry: It's War!

Gabriel Aubry vs. Halle Berry:

It's War!

Apparently, there's a reason why Gabriel Aubry recently panicked over his paternity.

The Canadian model filed a motion on December 30 to be officially, legally declared the father of Nahla, the two-year old daughter he shares with Halle Berry. Insiders tell Radar Online his concern over custody status is based on a series of explosive fights with his ex.

"Whenever Gabriel doesn't do exactly what Halle Berry tells him to do, or if he does something she doesn't approve of or like, she goes crazy on him, screaming and shouting," the source says.

Referring to Berry as someone with a "nasty temper," this friend says things grew more heated than ever near the end of the year, as Aubry was spotted out in public with Kim Kardashian and others.

"Halle was absolutely furious and had a complete melt-down. She basically gave him an ultimatum: choose between dating other women and carrying on being on her good side... in the end he just got sick of being bossed around and told what to do by his ex-girlfriend."

For that reason, Aubry can't trust that he and Berry can peacefully work out a custody arrangement outside a courtroom.

The source makes it clear that Gabriel believes Halle Berry is a good mother, and has no intention of fighting for full custody of Nahla. He just wants to ensure his rights as her father are protected, especially as Berry has allegedly gone to extreme lengths to discredit him.

"Gabriel Aubry told me that he believes Halle Berry is having him tailed by a private investigator, and he's not just some paranoid dude with a wild imagination... if she thinks a PI is going to dig up anything salacious or scandalous I think she'll be sorely disappointed. Gabriel's one of the straightest, nicest, bordering on boring guys I know."
