“The image they project simply isn’t reality,” explains the Our Brand Is Crisis star

She might be America’s sweetheart, but even Sandra Bullock has her limits – especially when it comes to social media.

The Our Brand Is Crisis star, 51, says she cringes at the idea of posting a slew of happy selfies for the world to “like,” because the image they project simply isn’t reality.

“We’re not representing our lives truthfully,” she tells U.K.’s The Times. “Like when you’re yelling at your child, you’re not taking a selfie of you being a horrible parent. No, you’re waiting for the perfect selfie. ‘Do I look thinner now?’ ‘Do I look great?’ It’s this false projection of one’s life. Hollywood has now gone global. Everyone’s Hollywood now.”

Bullock, who recently adopted daughter Laila, 3 ½ (she joins brother joins son Louis, who turns 6 this month), turns up her nose at the idea of the “selfie generation.”

“I hate taking selfies,” she says. “I will not take a selfie that I can’t erase. I don’t post or do any of that stuff.”

But that doesn’t mean the star is against taking family snapsH๏τs – privately.

Last week, the mother of two picked up a People’s Choice Award for favorite movie actress, and told the audience she keeps a trove of family videos on her smartphone. (She explained that Louis thought he should get an acting award for his starring role in the home movies.)

Bullock also told The Times that in the age of oversharing, less can often mean so much more.

“People have these worlds they post and it’s about projecting an image and getting likes,” she explains. “I read a great article about how there’s a higher rate of depression because people are looking at everyone else’s Facebook [pages] and seeing this picture-perfect life.

“I think it’s frightening for kids and young people developing who they are to have that false sense of acceptance based on an image,” she continued. “How do you unravel that when it’s being pushed hard?”
