"This is the Happiest Valentine's Day of my life," the 42-year-old former supermodel wrote alongside the picture. "York, Daddy @erikasla and I send you so much love."
No wonder the photo is such a stunner. While Banks is a skilled professional in front of the camera, her Norwegian beau of more than two years, Erik Asla, is successful behind it. Asla's photography has been seen in fashion magazines around the world.
Banks and Asla welcomed York, their first child together, in January, after a surrogate mother gave birth to him. The couple announced his arrival on Instagram with a picture of a tiny baby's beanie.
"The best present we worked and prayed so hard for is finally here," the America's Next Top Model star captioned the photo. "He's got my fingers and big eyes and his daddy Erik's mouth and chin. As we thank the angel of a woman that carried our miracle baby boy for us, we pray for everyone who struggles to reach this joyous milestone. York Banks Asla, welcome to the world."
