Zayn Malik and Gigi Hadid's daughter finally made her first Instagram debut since the day she was born, and a spooky one at that!

On Halloween, the new parents dressed up alongside their infant daughter, who was the Hulk; they cleverly covered the baby's face in the Instagram photo with an emoji of the Marvel character.

Her little green costume and green Hulk hat are, however, visible and very cute. Hadid shared the family shot on her Instagram story:

For her part, Hadid dressed up as the character Zero Suit Samus Aran from the Metroid science-fiction adventure game series. Malik was a Slytherin from Harry Potter.

This is the most we've seen of baby Hadid-Malik; her parents have been careful to keep her off of social media and have not yet revealed her name to the public.

When she was born in late September, her parents posted separate black-and-white photos of her hand wrapped around theirs.

"Our baby girl is here, healthy and beautiful🙏❤️," Malik wrote. "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"

The new family is staying at the Hadid family farm in Pennsylvania, where grandma Yolanda can lend a hand with the little one.

This past week, Hadid shared a thank-you note for her fans following her baby's birth:

"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 receive 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. 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"
