ISIS threatened to behead Lebanese-American porn star Mia Khalifa with a mocked-up execution photo, but she’s keeping up a brave front, she said.

The terrorist group sent a “photoshopped picture of me being beheaded” via social media, and “threatened that would happen to me,” Khalifa told radio hosts of The Sports Junkies Thursday.

ISIS allegedly sent the 24-year-old adult actress the disturbing image after she drew major backlash for starring in a number of clips performing sexual acts while wearing a hijab in 2015.

The mocked up shot shows the porn-star turned sports pundit’s head pasted onto the body of a prisoner in an image taken from an Islamic State execution video.

The formerly top-ranked Pornhub performer said she’s trying not to let it get to her.

“You can’t show weakness,” she said. “That’s exactly what they’re looking for.”

But she does have moments of doubt.

“I really try and just make it look like it rolls off, but I’ll admit, it gets to you after a while,” she added.

Khalifa’s controversial performances during a three-month stint in the porn industry catapulted her into the limelight.

She now lives in Austin, TX, and is a social media personality and cam girl with millions of followers on Instagram and Twitter.
