We got Gabby at LAX Tuesday ... on her way back from the Sundance Film Festival, where she dissed Stacey for suggesting the BET Awards should be canceled to make the Oscars more diverse. Gabby's reaction was the classic ... "Stacey Dash who?"
Watch the clip ... Ronda got dragged into this when photogs hinted Union and Dash's beef might get physical. Gabrielle also celebrated another victory ... her movie, "The Birth of a Nation" and a record-setting day at Sundance.
All she does is win.
