Musician Zayn Malik has pleaded no contest to charges that he harassed his girlfriend — supermodel Gigi Hadid — and her mother during a Sept. 29 argument at the family’s home outside Philadelphia.

Yolanda Hadid took to Instagram on Saturday morning to pay tribute to her mother, Ans van den Herik, who died at the age of 78. "RIP my guardian angel Mama," Gigi and Bella Hadid's mom wrote alongside a slideshow of black-and-white photographs of her late mother. "Thank you for loving me the way the way that you did and for making me the woman that I am today." "I wish I could hug you right now," Bella wrote on the photo.
