When the 46-year-old star took over the Instagram for her beauty company Living Proof for a day, she said she was "sweating bullets."
"I was so stressed out," Aniston recounted to People. ""It was too much pressure. For these Kardashians, it's a career!"
While she might not like social media, she acknowledges that the Kardashian/Jenner crew really know what they're doing in that arena.
Aniston went on to admit that, despite herself, she cannot help but be fascinated by the lives of the Kardashians.
"I sadly am very much interested in the Kardashian-Jenner thing," Aniston confessed. "That's a guilty pleasure for sure."
