So how did the two spend that special day?
"He surprised me with dinner," Gigi revealed to InStyle. "It was just really nice. We have the best time, and we love to try new food together. We cook a lot, so it's nice to get out and try new things that we don't make at home."
However Gigi also revealed that cooking for Zayn is one of her fave things to do. "My favourite thing to do is ask him something random that he wants me to make. I like challenging myself and seeing if I can make it. We do that a lot."
She even goes to Zayn's mum for help. "That's really fun for me. Just random things we see on food network, or his mum will send me recipes and I do it. It's a great way to get my mind off things when I have a day off."
Zayn and Gigi have been dating in 2015 when Zayn attended the Victoria's Secret Fashion Show that she was walking in. However, this year, both will be sitting the event out.
