She said: I'm not sure if it's your family tweeting for you.
Khan's verified account and a Twitter page purportedly belonging to Faryal duly traded insults and accusations, with the latter said to have "moved up in the weight classes" to see Joshua.
In subsequent tweets, former light-welterweight champion Khan added: "Left my family and friends for this Faryal".
Taking things to yet another level, Faryal later announced to her followers that Amir was now in Dubai with a prostitute.
In her scathing comeback to Khan's allegations that she was a golddigger, the Pakistani-American beauty, who celebrated her 26th birthday in July, accused him of using her and Joshua as a scapegoat for his failings.
Following these tweets he shared others telling his wife "you getting the divorce" and labelled her a gold digger.
He's given me jack s*** - I pay house bills and bills for my daughter myself!
And now Joshua has responded to the story, quoting Shaggy's 2000 smash hit single 'It Wasn't Me.
And he has the nerve to blast me like that?
The couple, who married in glamorous 1000-guest ceremony at New York's Waldorf Astoria Hotel, have a two-year old together called Lamisah, born in 2014. It can destroy you. But since I loved you at one point in my life. "But I'm not the one who been in the papers for cheating".
Within the last hour he posted the video to the chart banger and followed it with a tweet saying he has never met Amir's wife and he prefers "big handsome women".
The couple have faced allegations of his infidelity since their lavish wedding four years ago.
"Amir is a good guy, him and his wife have had some problems in the past but this isn't like him", the insider claimed.
Khan has been linked with a string of other women, including model Natalie Fox and Playboy star Carla Howe.
