BOXER Amir Khan has been hit by more personal turmoil after a long-rumoured sex tape of the star was leaked online.

The X-rated clip shows him in just a T-shirt and boxer shorts performing a sex act on himself while in conversation with a female model on the video call service Skype.

It is believed to have been made just weeks after the former world champ’s wedding to Faryal Makhdoom in 2013.

American Faryal, 25, was said to be “absolutely disgusted” by the video — which has been published on a major US porn website.

The woman in the footage is believed to have been from Arizona, USA, and first had a fling with Amir in 2010.

At the time, three further sordid videos of the boxer were being offered for sale to porn websites.

Several other British male celebrities are now braced for embarrassment after a mass leak of such tapes was threatened.

A high-profile ex-England footballer, BBC presenter and X Factor favourite are all said to be "panicked" at the prospect of X-rated clips being posted.

This new headache for Khan comes as Faryal remains at loggerheads with the Muslim fighter’s family after an explosive public feud.

A source revealed: “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.

“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.”

Beauty blogger Faryal’s feud with Amir’s family was exposed after she posted a long rant on social media accusing them of bullying her.

She claimed Amir’s sister had thrown a remote control at her and cropped her out of family pictures.

Amir’s parents then sparked a war of words by slamming her accusations.

But they admitted to demanding that she change her “unacceptable” dress code.

“Both parties need to stop this.
