Zayn Malik calls Gigi Hadid his ‘everything’ as he shares sweet tribute to his model girlfriend on her birthday

ZAYN Malik shared a sweet snap of him giving girlfriend Gigi Hadid a birthday kiss as he called her his "everything" as she celebrated turning 22 on Sunday.

The former One Direction star posted the picture to Instagram which showed him kissing the Victoria's Secret angel on the cheek.

He captioned the snap: "Happy birthday to my everything ❤️".

Gigi shared another cute shot of him kissing her while she holds a stunning pink birthday cake adorned with white flowers and chocolate icing.

She simply marked the photo with some heart emojis.

Naturally, the international supermodel marked her birthday with a glamorous day out and her model pal Hailey Baldwin took to Snapchat to share a picture of them enjoying a helicopter ride.

Gigi's sister Bella took a snap of her enjoying the view and wrote: "My queen living" and another of her clutching a bouquet a luxurious red roses.

Feeling the love, she wrote: "lucky bday girl :)".

The couple have been together for over a year and have kept fans guessing about their relationship status after Gigi was spotted with a sparkler on her ring finger last month.

Gigi first sparked wedding rumours in January when she showed off another band on her wedding finger.
