And then there were five.

"My Girl" singer Dylan Scott and his wife, Blair Robinson, welcomed their third child on Tuesday.

"Baby update," Scott said on Instagram. "Who is that?" he asked his children. They replied: "Barron." Then he asked them again, and they said: "Barron!"

Robinson held the baby in her hospital bed, and their children Beckett, 5, and daughter Finley, 4, admired their new brother.

"Oh look at momma, hot momma. Come on now," Scott said about his wife.

Scott said in the clips's caption that Barron was born at 7:19 p.m. Tuesday.

"Blair is a ROCKSTAR!" he wrote. "She did awesome! Beckett and Finley are in love, as well as Momma and myself! Thank you, Jesus, for blessing me with three healthy beautiful kids and a smoking hot rockstar wife! Life is good!"

The couple revealed they were pregnant in May and had announced the previous August that he and his wife were trying very hard to get pregnant with another baby.

"I always knew that I wanted one more, but I wasn't sure about Blair," Scott told People. "But then, the tables turned! I was thinking we were good, and Blair was the one who wanted to try for one more. It took a little bit of discussion, but we are both now on the same page… we need one more."

Scott and Robinson have known each other since they were children. They started dating in 2006 and got married in 2016.
