Gigi Hadid treated fans to her first selfie alongside boyfriend Zayn Malik and their newborn daughter.

The supermodel posed with her tot and beau as they celebrated their first Halloween together as a family of three, just weeks after giving birth.

Gigi, 25, and Zayn, 27, have not yet disclosed the name of their daughter but it is believed she was born at the Hadid family ranch in Pennsylvania in the midst of the coronavirus pandemic.

Posing in their costumes, the new parents looked over the moon as they posed for the latest family selfie as the identity of their daughter was covered by an Incredible Hulk emoji.

Victoria's Secret model Gigi opted to go for an Avatar inspired look, donning a blue lycra one-piece while Zayn, a huge Harry Potter fan went all out dressed as Draco Malfoy, rocking the Slytherin robe and tie.

Gigi, whose real name is Jelena captioned her Instagram Story: "My first Halloween."

Just last week, the mum-of-one took to her Instagram Grid to flaunt her post-baby body, encouraging her 60.3million followers to vote in the upcoming American Presidential election.

She captioned her post: "I voted absentee last week with my daughter next to me, for an America I want her to see; but not just for us - for fellow Americans that are less privileged, with hope for a nation that is unified, that is empathetic, & for a leader that is compassionate."

It's the first time the two have shared a snap alongside their daughter since announcing her birth last month.

In a heartfelt tweet, former One Direction singer Zayn penned: "Our baby girl is here, healthy and beautiful.

"To try put into words how I am feeling right now would be an impossible task. The love I feel for this tiny human is beyond my understanding.

"Grateful to know her, proud to call her mine, and thankful for the life we will have together x."

Gigi recently thanked fans and friends for the support she has received since becoming a parent, sharing a handwritten note saying: "I just want to put out there... While I have the time, that when I do Thank You's on here, I think of the so many generous gifts we have received that haven't gotten a public 'thanks'...

"I am overwhelmed with how many beautiful things this little one has already been spoiled with by people I love - and I will slowly probably share them."

She added: "BUT thank you cards are on their way - if I have not posted about something, it is not from a lack of gratitude. Just a new mom trying to get it all sorted while she naps!

"SO MUCH LOVE. SO MUCH GRATITUDE. WE ARE BLESSED. IF YOU HAVE SENT SOMETHING, EVEN A MESSAGE, THANK YOU. I LOVE YOU X G."
