"We're blessed and overjoyed to be welcoming a baby boy into the world and the third little boy into the MAFS family," the couple told Reality TV World in a statement at the time.
Deonna recently told Us Weekly that she couldn't wait for Greg "to have a little mini me," and Greg shared, "I can't wait to participate in father-son activities and watch him grow up to be a fine gentleman... like his dad."
During a Season 2 episode of Married at First Sight: Couples Cam that aired last month, a pregnant Deonna was shown giving her dog Bailey special attention and affection since her furbaby was no longer going to be her only baby in the house.
Deonna and Greg discovered they're going to be parents of a boy all the way back on November 1, but they clearly waited a while to share the news with fans.
"It's true, we're expanding our family!!" Deonna captioned an Instagram photo showing the couple holding a "Okotie Party of 3" sign that she posted shortly after Lifetime aired a Season 1 Married at First Sight: Couples Cam episode that concluded with Deonna receiving positive results of an at-home pregnancy test.
"What a blessing?! Thank you all for all of the well wishes and blessings on our family," she continued. "Yay! [Our dog] Sandy is going to be a big sister! #marriedatfirstsight #mafslifetime #teamparents #babyontheway #teamchocolateybaby."
