The 36-year-old actress was on a flight with Stacy Keibler earlier this month when the incident allegedly happened.
Stacy and George had hitched a ride on a private jet with Angelina and her partner Brad Pitt from Los Angeles to Palm Springs International Film Festival.
But a source told Us Weekly that there was some turbulence during the journey.
"Angelina refused to acknowledge that Stacy was even on the plane," an insider told the publication.
"Angelina went out of her way to ignore her, from take-off to landing. She would not even look Stacy's way. She was not having it!"
Another source said they were not surprised by what happened because, "Angie is really not a girlie girl."
In fact, the mother-of-six told Marie Claire last month that she does not have a lot of female friends.
"Well, I have a few girlfriends," she told the magazine. "I just I stay at home a lot. I don't do a lot with them, and I'm very homebound. But I don't know, I don't have a lot of friends I talk to. [Brad] really is the only person I talk to."
