Former world champion boxer Amir Khan secretly filmed himself having sex with a woman before threatening her, recently filed bombshell court documents seen by The Mail on Sunday claim.

The multi-millionaire sports star, who has twice appeared on I’m A Celebrity and is married to former model Faryal Makhdoom, is also alleged to have ‘sexted’ four other women, the papers show.

The legal papers, lodged at the High Court, form the defence of a women’s rights activist, Faaryal Hussain, in defamation proceedings brought by Olympic silver medallist Khan, 39, and Ms Makhdoom, to whom he has been married since 2013 and with whom he has three children.

The defence papers claim two of the women became depressed because of their alleged interactions with the boxer, with one posting a video online claiming she was left ‘suicidal’ after allegedly being threatened by Mr Khan.

The papers also contain claims from Mrs Hussain’s lawyers that Ms Makhdoom, 33, who starred in BBC Three’s reality series Meet The Khans alongside the two-time world champion and their children, personally threatened and harassed some of the women after discovering their alleged relationships with her husband.

The allegations about the couple – one of Britain’s most prominent celebrity Asian families, who split their time between the UK and Dubai – have emerged as part of a legal case in which the Khans are suing Mrs Hussain, who runs a campaign group called Our Voice.

Mrs Hussain went public with the women’s allegations in social media posts and in a podcast interview in 2023. She also launched an online petition to stop the boxer’s alleged ‘exploitation of women’.

The Khans strenuously deny all the allegations in the defence, claiming they are ‘false, defamatory and malicious’ and they will vigorously contest them at the High Court.

In the court papers the couple say Mrs Hussain’s statements led to financial loss and reputational damage, and caused the BBC to cancel the fourth series of Meet The Khans. They also claim that Ms Makhdoom was dropped from ITV’s Celebrity Big Brother in 2024 after Mrs Hussain’s allegations were published online.

This month, Mrs Hussain submitted her legal response to the Khans, which denies defaming them and claims the statements she made about them are true.

The Khans’ lawyers say that they intend to issue a formal reply to Mrs Hussain’s defence in the next two weeks.

It is not the first time that the celebrity couple have faced allegations of infidelity by Mr Khan during their 13-year marriage.

In 2018, he reportedly had a one-night stand with 22-year-old beautician Sophia Hammani, after meeting her in a London nightclub 17 days after the birth of his second child – allegations that he strongly denied and described as ‘total nonsense’.

A video also leaked online in 2017 reportedly showing Mr Khan performing a sex act, which he claimed was recorded ‘well before’ he wed Ms Makhdoom.

One woman, named in Mrs Hussain’s filed defence as Woman B, was allegedly contacted by Mr Khan around June 2022 on the social media app Snapchat, and messages continued on WhatsApp, Instagram and TikTok.

The court papers claim Mr Khan told Woman B, who is Asian, that he was unhappy in his marriage and sent her photos of his ‘intimate body parts’.

He is said to have arranged for her to travel to Dubai where it is alleged they had consensual sex on at least two occasions.

But on one occasion, it is claimed, Mr Khan filmed their encounter on a mobile phone without her knowledge or consent.

When Woman B discovered she was being filmed ‘she said no repeatedly and attempted to cover and hide her face’, according to the documents.

Mr Khan’s lawyers deny these claims, saying they are ‘false’.

It is further claimed in the papers that when Ms Makhdoom found out about the alleged affair, she contacted the woman and made disparaging remarks.

Ms Makhdoom’s lawyers say their client denies these claims.

Another woman, known as Woman A and described as ‘a beautician and social media influencer’ in the court papers, is said to have been contacted by Mr Khan on Instagram in May 2023.

The pair began chatting on WhatsApp, where he allegedly promised her financial assistance of £20,000 and allegedly asked her to come and meet him in Dubai.

The papers claim he also sent her intimate photos of himself.

But when Woman A refused to send him nude pictures in return, she claims Mr Khan told her he knew people in her home town – which she took as a threat.

She gave an interview to a Sunday newspaper about her claims three years ago.

After the story in the tabloid appeared, Mr Khan whisked Ms Makhdoom to the Greek island of Mykonos by private jet for a child-free luxury break and publicly apologised to her in statements to newspapers, saying he was willing to have ‘therapy’ to stop him texting other women. Mr Khan then claimed that he was being blackmailed during an interview with a well-known Pakistani satellite channel, Geo News, which allegedly led to Woman A receiving widespread abuse on social media.

As a result, according to Mrs Hussain’s defence, Woman A was left extremely depressed, uploading a video of herself on TikTok in a ‘suicidal’ state.

The Khans’ solicitors deny Woman A’s version of events and say the claims will, like Woman B’s, be addressed in the formal reply, which they are to file soon.

The defence of Mrs Hussain goes on to claim Mr Khan had previously sent intimate texts and photographs to another British woman, who the MoS has chosen not to name, in April 2022.

This allegedly stopped when her boyfriend discovered the messages later that month and contacted Mr Khan, threatening to go to the newspapers. The Khans’ lawyers deny any wrongdoing. The documents also claim Ms Makhdoom threatened to ‘name and shame’ another woman, called Woman C in documents, after discovering her alleged affair with Mr Khan in 2023. Her lawyers deny this claim as well.

A fifth woman received messages from Mr Khan on Instagram in August 2016, it is alleged. Later the same day, it is claimed, she was contacted by Ms Makhdoom on the social media app, who said: ‘If you dare message or call [Mr Khan] I will destroy you.’

Ms Makhdoom’s lawyers say this claim has no validity.

In the court papers lodged by Mrs Hussain, she says she was also harassed and threatened by people she believes to be associated with the Khans.

Her involvement with the couple began, she claims in her filed defence, when she was contacted by Woman A and Woman B in July 2023, which led to her posting on social media about their allegations.

She was subsequently contacted by the three other women before publishing her petition, a decision which she says was borne ‘out of a genuine concern for public safety’.

The petition, which has been submitted to the High Court as evidence, remains accessible online and has over 1,600 signatures.

But in their defamation claim, the couple say Mrs Hussain’s statements had caused ‘serious harm’ to their reputation, adding: ‘The stigma of these types of allegations is considerable, and long-lasting.’

The Khans are seeking an injunction against Mrs Hussain to restrain her from publishing any more allegations.

The MoS understands the case will be heard in January next year.

Last night Woman A, whose alleged experiences are detailed in Mrs Hussain’s filed defence, told the MoS that she has been ‘praying’ for the case to go to court, adding: ‘I have been waiting for my truth to be heard. If I need to, I will give evidence.’

Stone White Solicitors, acting for Mrs Hussain, said: ‘We cannot comment on an ongoing case.’ Central Chambers Law, acting for the Khans, declined to comment.

Last night the BBC declined to comment on an ongoing legal case, but added that Mr Khan will not be working on any upcoming projects at the Corporation.
