A student at the University of Alabama has been expelled from the school and kicked out of a sorority after she posted racist videos on social media in which she repeatedly used the n-word.

Harley Barber, a 19-year-old New Jersey native, identified herself on Instagram as a member of the Alpha Phi sorority at the university in Tuscaloosa, where officials are now investigating the “ignorant and disturbing” remarks, AL.com reports.

“These remarks are ignorant and disturbing and in no way reflect the values of The University of Alabama,” university spokesman Chris Bryant said in a statement. “This unfortunate behavior has been reported to the Office of Student Conduct as it does not align with the community expectations of students at the Capstone.”

Barber has since said she’s received threatening phone calls over her remarks and apologized.

“I feel horrible,” she said. “I feel so, so bad and I am so sorry.”

In Barber’s first video, she appears to talk to a bathroom mirror after turning off the sink faucet.

“We do not waste water,” Barber said. “We don’t waste water because of people in Syria. I love how I act like I love black people because I f–king hate n—–s. So, that’s really interesting — I f—king hate n—–s, but I just saved the f–king n—–s by shutting that water off.”

In a second video, Barber seemingly addresses a growing backlash to her first video and comments left on her “finsta,” or fake Instagram account.

“I’ve wanted to be in Alpha Phi since f–king high school and nobody f—king understands how much I love Alpha Phi,” Barber says, staring directly at the camera. “And now someone wants to save my finsta because I said n—-r? You know what? N—-r, n—-r, n—-r. I don’t care if it’s Martin Luther King Day.”

One female voice can be heard off-camera suggesting that Barber not post the video, but she continues spewing pure hatred.

“I’m in the South now, bitch,” Barber continued. “So everyone can f–k off. I’m from New Jersey, so I can say n—-r as much as I want.”

As of Wednesday, the second video of Barber had been retweeted more than 5,000 times. It also caught the eye of Alabama running back Damien Harris, who tweeted that Barber’s videos disprove the claim that “racism is dead.”

A spokeswoman for the Alpha Phi International Fraternity confirmed to AL.com that Barber has been kicked out of the sorority’s University of Alabama chapter because of the “offensive and hateful” videos.

In a telephone interview with The Post, Barber, originally from Marlton, 20 miles east of Philadelphia, said she was in the process of returning to New Jersey on Wednesday after being expelled from the university.

“I did something really, really bad,” Barber told The Post. “I don’t know what to do and I feel horrible. I’m wrong and there’s just no excuse for what I did.”

Barber has been getting threatening phone calls in response to the videos, which “came out of nowhere,” she said.

Asked if she considered the advice from one of her friends who suggested that Barber not post the videos, Barber replied: “No, I’m an idiot. There’s no excuse. I did something really bad.”

University of Alabama president Stuart Bell called the videos “highly offensive and deeply hurtful.”

“The actions of this student do not represent the larger student body or the values of our University, and she is no longer enrolled here,” Bell said in a statement. “We hold our students to much higher standards, and we apologize to everyone who has seen the videos and been hurt by this hateful, ignorant and offensive behavior. This is not who we are; it is unacceptable and unwelcome here at UA.”
