The teenaged girl whose sexting with Anthony Weiner helped shape the 2016 election is speaking out for the first time, telling Inside Edition that she played along with their creepy exchanges — until the disgraced pol included his young son in a bare-chested selfie he sent her.

At that point, “I was disgusted,” the teen says in the exclusive interview. “That was part of the reason I came forward.”

The teen, whose name is being withheld, says in an exclusive interview that she direct-messaged Weiner back in January 2016, as his wife, Huma Abedin, was at the peak of influence in the coming election as Hillary Clinton’s closest aide.

“I knew that Hillary Clinton would be running for president in the year 2016,” she tells Inside Edition. “I wanted to see if Anthony was still up to the same antics.”

She direct messaged him: “Hello, I’m a huge fan,” and Weiner snapped to attention, responding within “minutes,” she said.

Weiner soon moved past niceties, she said.

“He called me attractive,” she told the magazine, and wrote her, “You are kinda gorgeous” and “Your body is pretty insane.” Many of Weiner’s messages were too lewd to repeat, she said.

The teen also says that one day, over Skype, Weiner asked her to undress. Inside Edition isn’t letting on yet whether the teen says if she complied.

The 15-year-old North Carolinian eventually blabbed about the exchanges with a tabloid news site, prompting a federal investigation.

At one point, the FBI subpoenaed all of her electronic devices, she said.

And when the FBI examined the lewd, underage interactions on Weiner’s laptop, it also found a cache of emails from Abedin to Clinton — reopening the closed investigation into Clinton’s use of a private email server while secretary of state.
