Don't expect Julia Roberts to join Twitter anytime soon.
"It's kind of like cotton candy," she says of social media in an interview with Marie Claire."It looks so appealing and you just can't resist getting in there, and then you just end up with sticky fingers and it lasted an instant."
"I have too much potential for collapse. There's an anonymity that makes people feel safe to participate in hatefulness," she explains. "I like a good old-fashioned fistfight if people are pissed off at each other. I just feel like if you're really mad and want to have a fight, then put your dukes up."
A recent interview with Justin Timberlake echoed Roberts' fragility in the face of criticism. “Where did all this vitriol come from? It’s mean. And I’m not cut out for it,” he told GQ about critics' reaction to his new movie, “Runner Runner,” and his album, "The 20/20 Experience: 2 of 2."
