Carrie Underwood thinks social media is “not the real world.”

The 42-year-old singer has developed an effective strategy to deal with social media trolls in recent years, with Underwood revealing that she’s learned to “post and ghost” on platforms like Instagram.

Discussing her social media motto, the star tells E! News: “I stole that from Joe Rogan. It’s really important when you think about social media that you realize it’s not the real world.”

“It took me a long time to realize that, and a long time to be secure enough in myself to be like, ‘Do I care if somebody doesn’t like my hair today, or this thing I sang or how I sang it? I don’t.'”

Underwood insists that she has bigger, more important things to worry about in her life.

The chart-topping star, who has sons Isaiah, 10, and Jacob, 6, with husband Mike Fisher, adds: “I’m 42 years old. I’ve got two kids I’m trying to raise to be good humans. I’m just out there doing the best I can, so if I want to post something, I’m just going to do it and leave it there.”

Underwood rose to prominence after winning the fourth season of American Idol in 2005. She has since confessed to being “so naive” during her early years in the music business.

“Being on the show when I was 22 years old, every single week was like, ‘Do or die, now or never.’ I felt grateful that I even got the opportunity to get to be on the show, and I still feel like that now. I do get nervous for the hopefuls.”

“I do want everybody to win, but alas,” adds the “Inside Your Heaven” hitmaker, who is now part of the American Idol judging panel, says.

She has previously acknowledged that American Idol changed the course of her life.

“I went from nobody knowing my name to tens of millions of people watching the show,” she said when she announced the news that she’d be appearing on Idol. “I’m proud of everything that I was able to accomplish on the show and I’m so proud of everything I’ve accomplished since.”
