The Big Bang Theory ended with the dramatic reveal that Leonard and Penny were going to have a baby, and real life has imitated art!

Well, not for Penny, but for Johnny Galecki, who played Leonard!

Johnny and his girlfriend, Alaina Meyer, announced their pregnancy earlier this year.

They echoed the sentiment in an announcement on their own Instagrams.

"So happy to announce that we are having a baby! There couldn’t be a better blessing in the world for us and we are over the moon happy. We appreciate as much privacy in this time as we are celebrating with close friends and family, and we are happy to share the news with you," she wrote on her Instagram.

Johnny admitted that he had a bit of a preference for whether they were having a boy or a girl.

“I get a little bored looking exactly the same way for 9 and a half months every year playing Leonard,” he said on an episode of The Talk.

He revealed that he thought he might be manifesting a boy.

“So we wrapped and I threw some blue in my hair, then I got superstitious that I was manifesting a boy, when I kind of prefer a girl.”

“Don’t play this tape for my child years from now!” Johnny joked, which really was foreshadowing.

“So, I painted my nails pink to try to even out the energy there,” he said, but emphasized that obviously the only thing that really mattered to him was the health of his child.

Their gender reveal party was absolutely adorable.

They revealed a few months ago that they would be having a baby boy, after sharing a few pictures of the two of them covered in blue paint.

"A day I'll never forget," Johnny wrote alongside this picture.

Alaina shared her own shots from the party.

The couple revealed they planned to name their baby Avery at their baby shower.
