Zayn Malik just shared the absolute sweetest post on his Instagram to celebrate his girlfriend Gigi Hadid's birthday.

The ex-1D singer shared a cute snap of him giving Gig a birthday kiss on the cheek as he called her his "everything" and we can't even deal with how adorable it is.

He captioned it: "Happy birthday to my everything <3"
