Russell Dickerson is a proud papa.
The couple's baby boy was born at 3:23 p.m., weighing 10 lbs., 4 oz. He measured 22.5 inches long, the publication reported.
The new addition marks the first child for the pair who married in 2013.
Dickerson recently told Fox News, "How prepared can you be, honestly?" when asked about the fast-approaching birth.
The couple announced they were expecting back in April.
"THE DAD SHOES ARE OFFICIALLY OFFICIAL! WE’RE HAVING A BABY!!" Russell wrote on his Instagram at the time, while Kailey shared a mirror selfie of the two well into the pregnancy with the caption, “Getting’ REAL y’all.”
The “Blue Tacoma” crooner told Entertainment Tonight in August that he was “freaking out in the best way,” as the due date neared.
“It's like nervous excitement, I’m nervous about how this is all going to actually happen," he revealed, adding that Kailey was feeling "amazing."
"We already got him the little baby headphones for side stage,” Dickerson added. “Got him his little denim show jacket. He's ready."
