Body language expert Dr. Lillian Glass has told RadarOnline what the twos encounter really meant.
48-year-old Aniston decided to skip the red carpet at the 75th annual Golden Globes and was seen for the first time when she came on stage to present the award for Best Musical or Comedy with legendary actress Carol Burnett.
While Aniston was on stage, Jolie appeared to seem very uncomfortable and looked anywhere but at the stage.
A photo of the moment has since gone viral, which shows the moment.
Dr. Glass reveals, 'Angelina looks down and tries to smile but it is a very forced smile.'
'She holds her head to her chin to brace herself. Holding on to her chin is signal that Angelina was angry.'
Dr. Glass adds, 'Even though Angelina is trying to smile she cannot even bear to look at Jennifer!'
It is unknown if the two actually came face-to-face, but we're thinking by the look on Angelina's face it's unlikely.
