Aubry a model and sometime actor, was spotted with Kardashian at an L.A. Lakers basketball game in November.
They also caught a movie together, but the relationship never advanced beyond that, and Kim turned to pro baskeball player Kris Humphries.
But the episode was enough to trigger Berry’s concerns about who Aubry would be bringing into her daughter’s life.
“Halle was very upset,” a source told the magazine. “She was upset at the idea of someone like that being in her daughter’s life. She did not want a reality star in Nahla’s life. She was very aggravated.
“Halle couldn’t care less who Gabriel dates,” says this source. “She just didn’t want Nahla exposed to the cameras that are undoubtedly around a reality star.”
But a source close to Aubry said neither Kim nor Gabriel ever entertained the idea that Nahla would become part of the reality star’s act.
The incident apparently led Gabriel to seek formal legal custody of Nahla. Before that he and Berry were sharing informal joint custody.
From there, the split has degenerated into an ugly confrontation, with allegations of racial slurs, and screaming fits being hurled by both sides.
