A sex tape featuring former world champion boxer Amir Khan has reportedly been leaked to a major US porn site.
The X-rated video allegedly shows the Olympic silver medallist, 30, carrying out a sexual act while speaking to a female model on Skype.
It is claimed the video was made shortly after he married wife Faryl Makhdoom, 25, in 2013.
However, the accusations have not been confirmed or denied by Khan's representatives.
It is believed the woman from the footage is from Arizona in the US and first met the boxer in 2010.
There are also reports that three other X-rated videos of the boxer were being offered to porn websites, at the time.
A source told the Sun: '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.'
MailOnline has contacted a representative for Khan and is awaiting comment.
News of the alleged sex tape comes at a difficult time for the sports star with Faryl embroiled in a vicious feud with her husband's family.
The mother-of-one accused the Khan family of repeatedly bullying her and being violent towards her, leading to a very public spat at the tail-end of last year.
Faryl claimed that Khan's sister Tabinda grabbed her hair and slapped her head while she was eight months pregnant with daughter, Lamaisah.
But in the bitter war of words, his father Sajjad accused 'very evil' Faryl of inventing the claims.
He said she was a 'bad mother' for leaving her young daughter with her parents in New York over Christmas, to be with Khan at a training camp, and claimed his famous son would 'probably' divorce her soon.
In a recent interview, Faryl said she regretted her many social media outbursts attacking her husband's family, but insisted it was 'an anger that's built up over the years'.
She explained: 'They have been so unkind. I was in Pakistan with Amir's family when his brother tweeted: 'Michael Jackson isn't dead. He lives with us.' He was trying to say I'd had plastic surgery.
'I was pregnant with our daughter, who's now two, at the time. Can you imagine what it was like being in the same house with him when he was saying that?'
She went on to claim the very insular family felt threatened by her, an independent part-time model who owns her own cosmetic company, because they feared she would take Khan away.
She said: 'Every single one of them is married to a cousin or a relative. Amir's sister [Tabinda] is married to a relative from the village. Amir's brother's [Haroon] marriage was arranged with a relative from the same village.
'But Amir picked me because he fell in love with me. I was the first outsider, and asking me to marry him was the first big decision he made for himself. I think there was jealousy. He sent me so many gifts.'
'I believe they couldn't accept Amir had found someone who might take him away from them.
The former light welterweight world champion has amassed an estimated £30million since he won a silver medal in the 2004 Olympics in Athens at the age of 17.
