The 22-year-old model posted a clip Sunday on Instagram Stories of herself smooching Malik on their second anniversary as a couple.
The clip shows Hadid smiling and kissing Malik as she holds a drink with a strawberry garnish. The pair appeared to be out celebrating the occasion.
"2 yrs with my favorite human," Hadid captioned the post.
Hadid and Malik were first linked in November 2015, and made their red carpet debut as a couple at the 2016 Met Gala. Malik told the Evening Standard in June that he and Hadid are a "normal" couple despite their fame.
"I can understand how it can look, that you've got these two people in a 'power couple,'" the former One Direction singer said. "That's not something I want to be a part of. I'm with her because I like her."
"When we come home, we don't really talk about that [expletive]," he added. "We just spend time together as a normal couple, cook food, watch TV, have a laugh."
Hadid is known for her modeling work with Tommy Hilfiger, and will walk in the 2017 Victoria's Secret Fashion Show with her sister, Bella Hadid, this month. Malik released his debut solo album, Mind of Mine, in March 2016.
