Tyra Banks has shared the first photo of her baby boy.

Banks is expressing her joy on social media after welcoming a son, York Banks Asla, with her boyfriend Erik Asla last month via gestational surrogate.

"This is the Happiest Valentine's Day of my life. York, Daddy @erikasla and I send you so much love," Banks captioned an Instagram photo of herself cradling her child on Sunday.

The 42-year-old America's Next Top Model creator and judge revealed in September of last year she underwent IVF procedures in the hope of conceiving her first child.

Banks and Asla, a Norwegian photographer, experienced "very traumatic moments" during the process, as the supermodel was well aware it would be difficult to get pregnant considering her age.

Banks has been dating Asla for over two years now but doesn't feel the need to get married.

She's publicly voiced how crazy it is for society to find getting married three times the norm in comparison to not walking down the aisle at all.
