At the same time, they posted two black-and-white teaser pics to Instagram, one showing the back of their son's head, the other showing his tiny, precious feet.
"Welcome to the world little Robbie Ray," Black, 44, wrote. "Thank you for bringing so much love and light with you. And thank you to those who helped make our dream of having a family into this wonderful reality. ❤️#AFamily #HappyBirthday 👨👨👦"
Daley, 24, wrote, "27/06/18 • Welcome to the world our precious little Robbie Ray Black-Daley ❤️," continuing with, "The most magical moment of my life. The amount of love and joy you have brought into our life is immeasurable. Our precious son. ❤️👶🏼❤️"
The name "Robert" was chosen to honor Tom's late dad, who died of cancer in 2011. It is also Daley's own middle name.
