The 21-year-old model published a video to her Snapchat where it is seen that her pizza box was scanned at the security checkpoint at the airport.
Hadid's video was accompanied by her words, "I will forever remember the first time I had to send my pizza thru security.”
Later she published a photo from inside the airplane where her friends were enjoying pizza.
She wrote, “Gotta keep my girls happy.”
A few hours later the model posted another photo, this time showing her in a tight cocktail dress. Either she didn’t finish her pizza or her metabolism is good, as her figure looked slim and fit.
Hadid was staying in Monaco after the Cannes Film Festival. Alongside her bikini photos, she also shared a video of herself with a dog, which may be her new pet.
