Supermodel Gigi Hadid and singer Zayn Malik are parting ways. A disagreement between Malik and Hadid’s mother Yolanda apparently precipitated the breakup. People Magazine had the details.

The final decision to part seems to be based on a recent incident at the Hadid’s New Hope compound. A disagreement between Malik and Yolanda Hadid spiraled out of control. Yolanda Hadid claims it got violent and spilled over to involve a security guard.

Malik denies the implication that things got physical. He did, however, plead no contest to harassment charges filed in Bucks County court.

As a result, he was sentenced to 90 days’ probation on each count. He is to break all contact with Yolanda Hadid and complete anger management classes.

Malik addressed the charges on Twitter, writing that he “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.”

He also complained the case had been leaked to the media and called it a “private matter.”

Malik and Gigi Hadid, 26, have a one-year-old daughter together. A family friend said they will co-parent moving forward.

But she also confirmed, “They are not together right now.”
