Tyra Banks has finally revealed her newborn son, York. And he's such a little cutie!

The 42-year-old supermodel debuted a simple snap of herself holding her son on Sunday. The new mom wrote, "This is the Happiest Valentine's Day of my life. York, Daddy @erikasla and I send you so much love."

In January, the America's Next Top Model host announced that she and her boyfriend, Norwegian photographer Erik Asla, had a son via gestational surrogate.

At the time of the announcement, Tyra posted a photo of a tiny hat on Instagram and that, "The best present we worked and prayed so hard for is finally here. He's got my fingers and big eyes and his daddy Erik's mouth and chin."

She also made sure to thank the woman who made it all possible, "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."
