Gigi Hadid spent her 20th birthday today doing what she does best: modeling sexy swimwear!
The gorgeous model, who finally said goodbye to her teen years Thursday, has been hard at work all day on the set of a sizzling bikini shoot for Seafolly in Miami.
For the spread, the blond beauty rocked a variety of two-piece swimsuits, including a blue bikini that showed off her toned tummy, her perky bum and cleavage. Gigi, who appeared to be in a great mood throughout the day, also rocked a strappy multicolored look while lounging by a pool. Look how her crystal blue eyes match the water!
