Zayn Malik and Gigi Hadid have broken up after six years together. The news was reported by TMZ (opens in new tab) after Gigi's mother, Yolanda Hadid, claimed that Zayn "hit" her last week.

A source told "Entertainment Tonight" (opens in new tab) about the incident, "Yolanda and Zayn had a disagreement that turned hostile. Yolanda told people that Zayn hit her. Yolanda is very upset and is causing problems between Zane and Gigi. Gigi was not there at the time of the incident and had to hear both sides of the story."

Zayn, who shares a 1-year-old daughter, Kai (open in new tab), with Gigi, has issued a rare statement denying Yolanda's accusations; he told several media outlets, including TMZ: "I categorically deny hitting Yolanda Hadid and for the sake of my daughter, I decline to discuss any more details I decline to speak about the following." "I hope that Yolanda will reconsider her false allegations and move toward healing this family matter in private."

News of Zayn and Gigi's breakup broke after Yolanda's allegations surfaced, but sources contradict each other about the timing of the breakup. Several sources "close to the situation" told TMZ that it happened a month ago, while another told ET (open in new tab) that Zayn and Yolanda's alleged argument prompted the split.

"Gigi and Zayn split after the incident with Yolanda," ET's source said. 'They are co-parenting, but not together. They tried to make things work for their daughter, but it didn't work."

Zane and Gigi have each called for privacy in separate statements. A representative for the models told ET, "Gigi is focused solely on doing what is best for Kai. We ask for privacy during this time."

The singer said on Twitter (opens in new tab), "As you all know, I am a private person and I am very keen to create a safe and private space for my daughter to grow. A place where our family's private affairs are not thrown out on the world stage for all to poke and prod at."

"In order to protect that space for my daughter, I agreed a few weeks ago not to contest a claim arising from an argument with my partner's family who entered our home while my partner was away. This was and should remain a private matter, but there seems to be a division at the moment and this has been 'leaked' to the media despite my efforts to restore a peaceful home environment where we can co-parent in a manner befitting my daughter.

"I hope that the harsh words shared will help heal everyone involved and more importantly, I will remain vigilant to protect Kai and give her the privacy she deserves."
