Former One Direction singer Zayn Malik has denied "striking" Gigi Hadid's mother.
TMZ said the 57-year-old has accused Malik of an alleged assault last week. He has denied the allegations to the US showbiz website.
Malik, who has a one-year-old daughter Khai with model Gigi, 26, told TMZ: "I adamantly deny striking Yolanda Hadid and for the sake of my daughter I decline to give any further details and I hope that Yolanda will reconsider her false allegations and move towards healing these family issues in private."
He later wrote a post on social media, referencing the allegations while asking for privacy.
"As you all know I am a private person and I very much want to create a safe and private place for my daughter to grow up in," he said.
"A place where private family matters aren't thrown on the world stage for all to poke and pick apart. In an effort to protect that space for her, I agreed to not contest claims arising from an argument I had with a family member of my partner's who entered our home while my partner was away several weeks ago."

Seemingly hinting that he and Gigi had split, he wrote that he wants to "co-parent my daughter in a manner in which she deserves".
He said: "This was and still should be a private matter but it seems for now there is divisiveness and despite my efforts to restore us to a peaceful family environment that will allow for me to co-parent my daughter in a manner in which she deserves, this has been 'leaked' to the press.
"I am hopeful though for healing for all involved with the harsh words shared and more importantly I remain vigilant to protect Khai and give her the privacy she deserves."
A representative for Gigi also asked for privacy and said in a statement to E! News: "Gigi is solely focused on the best for Khai. She asks for privacy during this time."
Gigi and Bradford-born Malik have been dating on and off since 2015 and welcomed their daughter last September.
Yolanda, a Dutch-American TV personality best known as a star of US reality TV show The Real Housewives of Beverly Hills, has not publicly addressed the incident.
The former model is also the mother of models Bella, 25, and Anwar, 22, who is pop star Dua Lipa's boyfriend.
She was married to property developer Mohamed Hadid, 72.
Gigi had previously said that her mother and Malik got on well. "He's usually on my mum's side. So, he's smart in that sense," she told Harper's Bazaar.
Malik, who previously dated Little Mix's Perrie Edwards, launched a solo career in 2015 after parting ways with One Direction.
His most recent album, January's Nobody Is Listening, peaked at 17 in the UK albums chart.
