Singer Zayn Malik has pleaded no contest to claims of harassment after allegedly shoving model Gigi Hadid's mother into a dresser and calling her a sexual slur, court records show.
The former One Direction star, 28, is alleged to have launched a tirade against Dutch-American socialite Yolanda Hadid, 57, at his home in Bucks County, Pennsylvania, last month.
Malik and US catwalk star Gigi Hadid, 26, share one-year-old daughter Khai.
Court records obtained by the PA news agency allege the Bradford-born star told Yolanda Hadid to "stay away" from his daughter.
He is also alleged to have "grabbed and shoved" Yolanda Hadid into a dresser, "causing mental anguish and physical pain".
Malik issued a statement denying "striking" Yolanda Hadid.
Gigi Hadid, who has been dating Malik on-and-off since 2015, was in Paris at the time of the 29 September row, according to US showbusiness website TMZ.
Malik was also allegedly involved in an alteraction with security guard John McMahon.
Malik was charged with four counts of harassment in the non-traffic citation, which a court official said is not a criminal charge.
He pleaded no contest, meaning he does not admit guilt, but has chosen not to fight the charges.
The singer has been placed on 90 days' probation for each count for a total of 360 days, the citation filed in Pennsylvania shows.
He must also complete an anger management class and a domestic violence programme, as well as having no contact with Yolanda Hadid or John McMahon.
If there are no further issues, a judge could terminate the probation after six months.
Malik and Gigi Hadid had been living at a farmhouse in Pennsylvania. People magazine reported the couple have split.
The row became public knowledge on Thursday when TMZ reported Yolanda Hadid had accused Malik of assault.
In a statement to the outlet, Malik said: "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 issued a further comment on social media, saying a family member of Gigi Hadid's had entered their home while she was away.
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 Hadid said: "Gigi is solely focused on the best for Khai. She asks for privacy during this time."
Yolanda Hadid, a former model best known as a star of US reality TV show The Real Housewives of Beverly Hills, has not publicly addressed the incident.
Yolanda Hadid is also mother to the models Bella, 25, and Anwar, 22.
She was married to the property developer Mohamed Hadid, 72.
Malik launched a solo career after leaving One Direction in 2015.
His most recent album, Nobody Is Listening, was released in January.
