Gigi, 28, also couldn’t help but to marvel at how quickly time flew by in her birthday tribute to Khai.
“Have been celebrating our THREE YR OLD this week,” she wrote on Sept. 20, sharing photos of her daughter through the years. “& just so honored to get to be her mama, to get to see life through her!!!!”
Calling Khai the “DREAM KID” and “love of my life,” the supermodel added, “Happy Birthday to my sweetest, smartest, spunkiest bestie!”
The precious post also gave a glimpse into how the mother-daughter duo celebrated Khai’s milestone, with Gigi posting a snap of another Frozen-inspired birthday cake.
