Bella Hadid shared a video homage of herself with fans to celebrate her 21st birthday.

Taking to Instagram on Monday (09Oct17), Bella uploaded a 30-second clip of herself posing for the camera on numerous different fashion shoots.

Set to Justin Bieber and Big Sean track No Pressure, Bella showed off her flawless figure in different skimpy outfits, and also paints her famous pout with red lipstick in one scene of the video.

“I was born 21 years ago,” she captioned the video, which has so far racked up over one million likes.

In a second video, Bella, wearing a simple white dress, poses and sings to herself in the mirror while someone films from behind.

Bella’s model sister Gigi also chose Instagram to wish her younger sibling a happy birthday.

Sharing a sweet picture of Bella captured as a newborn, Gigi told her followers on Sunday: “TOMORROW WILL BE 21 YEARS SINCE I MET MY FOREVER BESTIE @bellahadid (me wearing all red on your actual day of birth is MAJOR and possibly the reason it's your favorite color)."

In a second snap of the pair as children, the 22-year-old catwalk star shared a gushing message to Bella.

“HAPPY 21st BIRTHDAY MY ANGELIC SISTER @BELLAHADID !!!” she exclaimed. “There are no words for how much I love you. You know I've been trying to protect u from the world since day one, and 21 years later u comfort and inspire me more than you'll ever know.
