Stunning Faryal Makhdoom has been embroiled in a bitter feud with the family of her boxer husband since early December.
The public has had a ringside seat to the row that was triggered by accusations of bullying from the 24-year-old model.
Now the Pakistani-American, 24, has opened up about the incident after a month of in-fighting between the Khan family.
Relations reached a new low when Amir’s dad Shah Khan, 54, branded Faryal a “very evil woman” for ruffling feathers in family.
But speaking to the Daily Mail, Faryal said “it’s not just the parents” who have caused her grief.
She claimed to the paper: “I wonder if the older daughter [Tabinda] was filling the parents’ heads. She lived a block away in Bolton, but was always in our house.
“She was very controlling and I remember her saying once: ‘You’re supposed to live with Amir but at any excuse all you do is f*** off to your mum’s in New York’.
“I said: ‘You’re the last one to talk. You’re married but you’re always here at your mum’s house.’
“She grabbed my hair and slapped my head. I was eight months’ pregnant. I told Amir but he didn’t believe me because he couldn’t believe me.”
“She grabbed my hair and slapped my head.”
In an explosive interview with This Morning earlier this month, Faryal claimed the Khans scorned her for looking “fake” like “Michael Jackson”.
Later it was revealed Amir’s brother tweeted: “Michael Jackson isn’t dead. He lives with us.”
But Faryal insists she had “never had plastic surgery” only “fillers in my cheeks and my lips”.
Shah, who used to live with Faryal and his son in Bolton, branded her “crazy” for spilling the beans on national TV instead of trying to make amends.
He blamed the New Yorker for the feud claiming his son may split up with her “sooner rather than later”.
But Faryal claims her husband’s close-knit family refused to embrace her from the off.
“I believe they couldn’t accept Amir had found someone who might take him away from them,” she said.
She claims the Khans asked her to sign a prenup – a contract prior to marriage – two weeks before their wedding to protect Amir’s finances.
She said: “In our culture, to ask a bride to do that is very disrespectful. One of his team gave it to me when Amir was in the training camp.
“I signed it because I wanted to prove I didn’t want the money. I wanted Amir. He is the love of my life.
“When I was pregnant, Amir cancelled the pre-nup.”
Earlier this month it appeared relations were on the mend between Faryal and the Khans.
Drawing a line under the dispute at a charity event in the US, Amir said: “Everything is fine in the family.”
But it appears Amir’s younger sister isn’t prepared to let bygones be bygones just yet.
Mariyah Khan, 19, appeared to lash out at Faryal in another cryptic jibe shared with her 103,000 Instagram fans.
The post read: “It read: “biggest lesson learnt this year is probably to not give so much of yourself to people who will not do the same for you”.
