Rep. Alexandria Ocasio-Cortez admitted that she gives “zero” f–ks when her Democratic colleagues criticize the youngest woman elected to the House for speaking her mind.

Appearing on “The Late Show with Stephen Colbert” on Monday, she was asked about how she feels when other Democrats admonish her by saying “Wait your turn” and “Don’t make waves.”

Colbert asked: “I want to ask this question in a respectful manner, knowing also that you’re from Queens, so you will understand this question. On a scale from zero to some, how many f–ks do you give?”

“I think it’s zero,” the 29-year-old said.

Ocasio-Cortez, who has become a force on Twitter and amassed more than 2.5 million followers, said she doesn’t always fire back at her critics on the social networking site because she doesn’t want to go after “some innocent bystander.”

But “If you have a blue check, if you’re in my mentions, if you’re being sassy in a way that I think is unjustified, and if I haven’t eaten in two to three hours,” she said she will.

The freshman lawmaker was enlisted last week to give Democrats some pointers on how to use social media to their advantage.

“Rule No. 1 is to be authentic, to be yourself and don’t try to be anyone that you’re not,” Ocasio-Cortez said on the show. “So don’t try to talk like a young kid if you’re not a young kid.

“Don’t post a meme if you don’t know what a meme is — that was literally my advice, and I said don’t talk like the Founding Fathers on Twitter.”
