Bella Hadid Wishes Sister and ‘Built in Best Friend’ Gigi a Happy 29th Birthday with Childhood Snaps

Bella Hadid is paying homage to her sister Gigi Hadid on her birthday!

As Gigi turned 29 on Tuesday, April 23, Bella, 27, called her older sister her “built in best friend” and "birthday girl" in a tribute on Instagram featuring a series of sweet childhood photos of the pair, including a photo of Gigi as a toddler holding a newborn Bella in the hospital.

Gigi, who sported cute mini pigtails in the snapshot, stared adoringly at her sister as their mom Yolanda Hadid watched on from her hospital bed. 

The supermodels siblings were seen embracing in the next image as they sported matching white tutu dresses and floral headbands, with Gigi wearing a blue one and Bella a pink one. The sisters even had matching frowned expressions as they both stared off to the side of the shot.

Bella and Gigi were snapped in more identical looks — with matching blonde hair — as they posed together and embraced while wearing blue tutu dresses, large sunhats with white coats and white furry shrugs.

The sisters were also captured in another cute shot sporting checked headscarves in red and pink as they sat next to each other in their swimming costumes outdoors with their backs turned to the camera. Young Bella wore an orange swimsuit, while Gigi wore a white tankini with her hair in pigtails. 

A final black-and-white photo showed the pair posing together at the 2016 Victoria’s Secret Fashion Show, where Bella made her debut alongside her sister. Gigi wore a black harness bra with lace as Bella modeled an embroidered bra and darker hair.  

On her Instagram Stories, Bella added in a message to her sister, “Happy birthday my jelly bean @gigihadid,” referring to her nickname for Gigi.

Alongside her message, she shared a throwback photo of the pair smiling together as flower girls at a wedding. The sisters wore matching white dresses and white and blue floral headbands as they held bouquets of the same color. 

Bella shared one last childhood photo of herself as a toddler with her sister as they sported very different-looking outfits this time, adding the emojis, “👯🪽.” Gigi wore a black and red printed top and her hair loosely, while Bella donned a pink collared sweater and sported a mini ponytail.

Bella's birthday tribute to her sister comes after celebrating her boyfriend Adan Banuelos' birthday earlier this month. On April 8, the model shared photos and videos of the pair together on her Instagram Stories as she wrote, "happy birthday my love..."
