As the Friends alum, 54, walked the red carpet in a custom black Dolce & Gabbana gown at the Sunday, January 7, awards show, social media users could not help but point out how Aniston may have still been healing from the shocking death of her sitcom costar Matthew Perry.
"What happened to our Jennifer Aniston?" a second user added of the Hollywood star's demeanor.
"Why are so many actresses looking like they're holding back tears?" a third person chimed in about Aniston.
The more low-key appearance comes months after the tragic passing of her longtime friend Perry, who was found unconscious in a hot tub outside of his Los Angeles home on Saturday, October 28, 2023.
According to authorities, the 17 Again actor's cause of death was due to acute effects of ketamine while drowning and coronary artery disease. Perry had been open about his past struggles with drug and alcohol addiction, though it's unclear if he was using ketamine recreationally or for treatment.
