They have been dating ever since they clicked in 2015 on the set of his steamy music video for the racy single Pillow Talk.
And it looks like Gigi Hadid and Zayn Malik have taken a serious turn.
On Friday the 21-year-old model was seen makeup-free as she took his mother Trisha and her sister Doniya to Disneyland in Anaheim, California. Not pictured was the former One Direction star.
The Vogue darling was covered up in a blue Disney blanket to fed off the chilly night air at the outdoor park as she looked at her cell phone.
Zayn's mother had on a black, red and white silk blouse and sunglasses on her head.
The group was being guided by private Disneyland tour leaders.
The leggy supermodel was also seen inside a Disney store outside of the park.
She was wearing a funky black hat and was surrounded by other Disneyland revelers who did not seem to recognize her.
This sighting comes after her mother Yolanda Foster blew up at Rebecca Romijn.
Yolanda slammed her fellow former model after Rebecca appeared to suggest that 'social media stars' such as Gigi Hadid and Kendall Jenner were 'not true supermodels'.
On Friday Yolanda fired back on Twitter, claiming the girls were 'Kind, hard working and they accomplished more at half your age in the fashion industry'.
After being asked on Entertainment Tonight what she thought of models such as Kendall and Gigi who are 'more famous for their social media presence than their runway experience,' Romijn said it was 'very frustrating' and that a lot of fashion insiders 'can't stand it'.
Rebecca said: 'Hate it that these, you know, social media stars are now the supermodels in fashion. They are not true supermodels.
