A profile of the boxer, who welcomed his second child with wife Faryal Makhdoom last month, has been spotted on private dating app Raya.
The 31-year-old and former I’m A Celebrity contestant appeared to advertise his availability on the profile, although its authenticity is yet to be verified.
The “private membership-based community” app features an exclusive reel of celebrities and high-profile singles.
Khan’s profile appears to show him sporting his signature fierce gaze and clenched hands in the shirtless head-shot.
The page also reportedly displays Khan’s Twitter handle and current place of residency, San Francisco.
The former Olympic boxer last month came under fire after allegation that he had an affair with beautician Sophia Hammani after they supposedly met at a club in London.
The 22-year-old claimed Khan told her he was divorcing wife, adding that she felt “so used” after she found out and reportedly then reached out to Makhdoom.
Khan however, slammed the claims on social media after the story emerged.
He wrote: “What total nonsense! She was wanting a pic but was told to
Khan added: “Quite strange at the fact that there is no photos of us together. Supposedly, I gave her £20, is that all she’s worth?”
