Suzi Mann, who has presented BBC Asian Network’s Official Asian Music Chart Show, claims she was sent messages by Khan, 36, after they first met in 2016 when she hosted a concert in Manchester.
She said that following their encounter, Khan repeatedly messaged her on WhatsApp ‘flirting’ with her and ‘making sexual advances’, which later escalated when he began calling and leaving her voicemails.
The single mother said she did not feel ‘comfortable’ with his messages and she ‘remained professional’ by choosing not to ‘entertain’ his behaviour.
The allegations come in the wake of news that Mr Khan had separated with his wife Faryal Makhdoom over a sexting scandal after the sportsman allegedly begged a model to send him revealing pictures.
Amir Khan’s representatives told MailOnline there was ‘no truth’ to Ms Mann’s allegations.

Suzi Mann posted the allegations of Mr Khan’s behaviour to her almost 19,000 followers on Instagram earlier this week.
She said: ‘I first met Amir Khan in 2016 whilst I was hosting Arijit Singh in Manchester!
A couple of days after the concert, I started receiving WhatsApp messages from an unknown number, with someone claiming to be Amir Khan!
‘I immediately had to ask, actor or boxer? Unfortunately it was the latter!
‘On a more serious note, these messages continued and then I started to receive calls and voicemails from Amir Khan himself.
‘Now I’ve been in this industry too long to not know when someone is flirting and making sexual advances.
‘This was not something I felt comfortable with and I chose to not entertain it, but remained professional.
MailOnline has contacted Suzi Mann for comment.
The allegations come in the wake of news that the couple had separated over a sexting scandal
The sportsman allegedly begged a model to send him revealing pictures and meet up with him ahead of their 10th wedding anniversary
Last week, MailOnline revealed that Amir and Faryal, 31, have separated and are said to be splitting their time between their homes in Dubai and Britain while Faryal decides whether she wants to end their 10-year marriage.
A source close to the Khan family told MailOnline: ‘Faryal is taking time to think about whether or not to walk away. She’s going through a very difficult time and choosing to focus on her children while she and Amir continue to co-parent.’
But yesterday Khan hinted at a reunion with his wife.
Taking to Snapchat, the boxer posted a clip in which he revealed he was at a private cinema with his estranged wife and a camera crew, saying: ‘We’ve just come into the cinema. It’s a nice little private one this.
‘Everything else is good just came with Faryal and the crew here to the cinema. We’re just chilling doing our thing.’ Faryal also posted an image in a cinema.
Last week, MailOnline revealed that Amir and Faryal, 31, have separated
Amir, whose marriage has been dogged by a number of cheating claims, allegedly contacted a model named Sumaira, 25, on May 6, three days after he was shown being evicted from the pre-recorded I’m A Celebrity… South Africa.
After he commented on her tattoos on one of Sumaira’s Instagram Stories, she is said to have replied: ‘I don’t know if you’re joking.’
Father of three Amir responded: ‘Lol I’m serious. They sick. (As) in good.’
She later sent him a picture of herself fully clothed but displaying roses on her midriff, to which he allegedly told her: ‘Can’t stop looking.’
Seemingly suggesting she send some more, he insisted it was a ‘tattoo chat’, reportedly adding: ‘It’s nothing I ain’t seen b4 . . . somebody’s body.’
Sumaira then claims they spoke on the phone, during which he attempted to explain why he had contacted her, saying that ‘he and Faryal were not properly together and that it was a bit of a business arrangement’.
She claims he spun a ‘sob story’, saying that he was retired from boxing and Faryal spent a lot of time in London.
The pair then stopped messaging and he claimed he was travelling back to London on May 8.
Khan has admitted he ‘regretted’ messaging Sumaira revealing he’d contacted her out of ‘boredom’ and telling The Sun newspaper that he’d go through therapy to stop him sexting other women.

Earlier this week, a new woman also claimed she had an affair with the boxer over four months – which only ended when Faryal threatened to ‘name and shame’ her.
The unnamed woman has revealed that the champion fighter admitted his marriage was ‘on the rocks’ and said that she slept with him this year after he demanded ‘no holds barred’ sex.
The woman reportedly said she met with Amir on several occasions, but that their fling ended when she received a call from his furious wife.
The couple have gone through a tumultuous time recently after Faryal posted a lengthy statement in response to her husband’s text exchanges with model Sumaira.
Stating that she ‘refuses to play out my marriage publicly,’ Faryal wrote on Instagram that ‘after a long week of accusations, slander and harassment I have decided it is now time to address the situation that has unfolded.’
Faryal described Sumaira’s actions as a ‘hate campaign’ and has denied that she is ‘responsible for Sumaria’s current mental state.’
Implying that she is standing by Amir, Faryal went on to state that ‘the whole world is aware of his track record’ and insists that Sumaira must have been aware he was married when she sent him revealing photos.
