A sex tape featuring Pakistani-Briton boxer Amir Khan has reportedly been leaked to a major US porn site.The X-rated video allegedly shows the 30-year-old British-Pakistani boxer carrying out a sexual act while speaking to a female model from Arizona, US on Skype.It is believed the woman from the footage first met the boxer in 2010 and that the video was made shortly after Amir married wife Faryal Makhdoom in 2013. However, the accusations have not been confirmed or denied by Amir's representatives.There are also reports that three other X-rated videos of the boxer were being offered to porn websites, at the time.“This is a mortifying moment for Amir. He's a Muslim boxer and his personal life is under the microscope right now, so the timing couldn't be worse,” a source told the Sun.”There had been rumours about these videos for years but now anyone who wants to view them on the internet for free can do so.”The videos have been leaked at a time when Amir's personal life is in turmoil. His wife, Faryal Makhdoom, recently took to Snapchat and spoke out against her in-laws and domestic abuse she had been facing after her marriage. The mother of the Olympic silver medalist rejected the allegations.In November, Amir was the victim of a failed blackmail attempt, with an extortionist claiming to possess a video of the 29-year-old with a woman.According to Daily Mail, Hamza Din, who emailed the Brit’s management team, stated earlier that the video showed the 29-year-old boxer with a woman in a hotel room in Newcastle.However, after the blackmail attempt failed, Din said that the footage did not exist and was given a suspended sentence by the Bolton Crown Court. Previously, Din claimed that the footage was "100 per cent real" and threatened to release it if he heard no response from Khan or his management team. He demanded money and said he would release the clip to the media unless they ‘matched the price’ it could fetch.This article originally appeared on Daily Mail
