Galecki wrote: “With full and grateful hearts we welcome our beautiful son into this incredible world. Thank you for all of your love and support."
The couple made the announcement they were expecting at a gender reveal party in May.
“To all those who voted boy you were right!” Meyer wrote on Instagram.
“A day I'll never forget,” Galecki said.
Johnny had earlier revealed during an appearance on chat show The Talk that he had been hoping for a girl.
"I get a little bored looking exactly the same for nine and a half months every year playing Leonard, so we wrapped and I put some blue in my hair," he said.
"Then I got superstitious that I was like manifesting a boy... when I kinda prefer a girl... don't play this tape for my child years from now... so I painted my nails pink to kinda even out the energy there."
Galecki played Leonard Hofstadter on the hit show.
