FORMER porn star Mia Khalifa says she "didn't make any money" off the infamous hijab sex scene that prompted ISIS to send her terrifying death threats.

The 28-year-old has opened up about her brief but turbulent career in the adult entertainment industry, which she exited after just three months in 2015 because of the threats from the terrorist caliphate.

Speaking on the latest episode of the Call Her Daddy podcast, Khalifa described her 90-day stint in the porn industry as the "worst time" of her life.

The Lebanon-born star, who was raised Catholic, went viral back in 2015 after she filmed a sex scene while wearing a hijab.

Though she rarely talks about the infamous clip, Khalifia, who was 21 at the time, previously revealed that the was told to wear the religious garment by the producers of the film and she "didn't realize she could say no".

Within weeks of its release, Khalifa was inundated with messages of abuse online from members of the Islamic State.

ISIS shared a manipulated image of her, showing her about to be beheaded by an ISIS executioner, with a message warning she's going to Hell.

The terror group also hacked her Instagram and posted jihadi propaganda on her feed before the social media giant shut down her account.

The address and a photo of her apartment were also widely shared online.

Revisiting that time of her life in the Call Her Daddy interview, Khalifa explained she was "disassociating" at the time she received the threats and was in the habit of just "pretending things like that didn't happen."

Host Alexandra Cooper asked Khalifa to describe "who that girl was" at the time the video went viral, and subsequently provoked outrage.

'To have the most isolating feeling, you're alone, you have people sending you death threats and your family at the time not supporting you, how did you get here today? A lot of people wouldn't have been able to get through that,' Cooper asked.

Khalifa responded: "So, I don't know where I was because that is around the time I started disassociating and just compartmentalising and pretending like things never happened to the point where I didn't talk about porn for the first like three years after, I just went quiet and never spoke about it.

"Every time I did an interview that was the one thing they were not allowed to ask me about, I refused to acknowledge that I did it and it wasn't until therapy that I realised how detrimental that is."

After undergoing therapy, Khalifa said she realized she couldn't keep "scooching things under the rug" and realized she needed to address what happened to her "head on".
