We knew something had to have happened to kick Halle into Baby Mama overdrive.

And basically, it came down to Fraud-y Aubry forgetting that he doesn’t have a job and refusing to do exactly what Halle wanted.

Halle Berry’s latest movie was supposed to be the big-budget romantic comedy New Year’s Eve – but for the actress and her ex, Gabriel Aubry, the feel-good film may have been the final straw in their already-strained custody arrangement over their 2 ½-year-old daughter Nahla.

According to a source close to Berry, the actress’s movie contract included compensation for Aubry to accompany her and Nahla to New York City for about two weeks of filming. But when Aubry decided not to go, says the source, Berry was forced to abruptly pull out of the film. She has since been replaced by Katherine Heigl.

Berry, 44, who has a nanny, currently shares custody of Nahla with Aubry. She pulled out of the New Line production not because she wouldn’t have childcare help but because she was concerned about leaving Nahla in L.A. while she filmed in N.Y.C., claims the source.

“When Gabriel refused to go, that became a factor in her decision to pull out of the film because she didn’t feel right leaving Nahla,” says the source. “No job is that important to Halle. Nahla comes first.”

The bitter custody battle is a far cry from the exes’ arrangement of only last summer, when Aubry accompanied Berry and Nahla to South Africa while the Oscar winner filmed her upcoming thriller, Dark Tide.

In other words, Garbri-el (pronounced with French accent), don’t all of a sudden act like you have something better to do than go to NYC on someone else’s dime. That’s been your life since 2005.(bossip)Tweet
