Robinson took to Instagram on Tuesday to share the happy news, revealing that daughter Lucille Ruby Odom was born on Sunday.
"Lucille Ruby Odom came into this world on Sunday, April 23rd, 2017. ? She is the love + light of our lives and she's teaching us so much already... Our sweet Lucy ?," the 29-year-old actress wrote alongside a photo of herself cradling her baby girl. "Mommy & Daddy couldn't be happier."
Odom also shared a couple adorable snaps of his newborn, announcing that he was "deeper in love by the minute."
"Lucille Ruby arrived in the wee hours on Sunday morning after a brief but harrowing labor on the part of her incredible mother, Nicolette Kloe Robinson, the dragonslayer," he captioned the slideshow on Instagram. "Deeper in love by the minute."
Odom and Robinson, who announced they were expecting last October, tied the knot in December 2012.
