While Aniston's husband joined Instagram not too long ago, she is adamant that she wants nothing to do with social media. "We work so hard to maintain some sort of life and privacy, why would we intentionally put ourselves out there?" she explained. "It's like you’re on TV or on a movie screen. [Fans] see you, hold their phone right up to your face, and take a picture. I’m like, I’m standing right here with a pulse! It’s sweet, though, just…different."
