Johnny Galecki, best known for his work on the hit TV show “The Big Bang Theory,” quietly married his wife Morgan Galecki — and even welcomed their first child.

Galecki, 48, made the revelation while chatting with Architectural Digest about her brand new Nashville mansion for their upcoming March cover story.

The actor did not reveal when they tied the knot or when their daughter was born.

Morgan was pregnant at the time of the couple’s photoshoot and “shortly thereafter” gave birth to their daughter, Oona Evelina.

The in-depth profile included stunning shots of Oana Evelina’s nursery, which included an animal-themed wallpaper, a giant beige rug, a giant stuffed rabbit, an RH cabin bed and a leather-tiled ceiling.

Galecki shared the profile on his social media, which also revealed a rare glimpse of his 4-year-old son, Avery, who he shares with ex-girlfriend Alaina Meyer.

“Thank you to @archdigest @tycole @colson__horton and @rachwall_ for the lovely profiles on the beautiful backdrop of our lives as they stand and smile today,” the actor wrote on Instagram. “We will put it in our family time capsule and cherish it for many years.”

Galecki purchased the Tennessee estate in 2018, but didn’t fully move into the property until 2020, just before the COVID-19 pandemic began.

He further said, “I say this with sadness, not with arrogance.” “Thirty years is a long time to live in a city you’re not comfortable with at all.”

Since “The Big Bang Theory” ended in 2019 after 12 seasons, Galecki has remained relatively out of the spotlight. In 2020, it was revealed that she and Mayer, 27, separated after almost two years of dating.

The “National Lampoon’s Christmas Vacation” star has kept quiet about her marriage, other than the occasional Instagram photo.

Recently, the couple and Galecki’s son took a trip to Disney World. Avery wore a Star Wars Stormtrooper mask while Morgan rested her head on his shoulder in the sweet photo.

“#absolutehappiness Thank you Mickey and the gang for a magical holiday after holiday,” Galecki wrote in the Instagram caption on January 13.
