Accusing Mia of punching him on face, the man posted a snap of his apparently bruised face and tweeted alongside, "Got a pic with Mia Khalifa and she punched me in the face and left a bruise."
The tweet has since been in the news and trending on the micro-blogging site, with many of Mia's fans coming up to her defence. One Twitter user posted a selfie with the former porn-star and wrote, "Can't relate".
In response, Mia wrote, "You were the sweetest. Thank you for asking me nicely rather than jumping in front of me while I was walking and shoving a cam in my face."
On a same note, the 24-year-old shot to fame in her native Lebanon, back in 2014, when she got intimate on camera, wearing a hijab. Despite quitting the X-rated acting scene last year, Mia is still one of the most popular adult stars on Pornhub
