The new mom – who welcomed her baby girl Khai last September – shared a picture to her Instagram story of the sweet gift Khai's dad Zayn Malik got her for her big day. The 28-year-old singer sent the supermodel a stunning floral arrangement consisting of roses, pink hydrangeas and more – leaving Gigi writing, "Wow." Zayn wasn't the only one who celebrated Gigi's birthday this year. She also received love from her sister Bella Hadid, who shared a candid photo of the two having a blast at the 2018 U.S. Open and wrote "Happy almost birthday." In addition, Gigi's dad, Mohamed Hadid, shared a cute snapshot of Gigi as a baby with a naturally model-esque pout. Dua Lipa, who is dating Gigi's brother Anwar Hadid, also posted a photo of the two of them to her Instagram story, writing, "National @gigihadid day. Happy Birthday sweeeeet thing!" Gigi, who re-shared the photo, thanked the Levitating singer, adding to the post, "THANK U SISTER ILY." Last year, Gigi celebrated her 25th birthday on her family's farm in Pennsylvania with Zayn and the rest of her family.
