‘Big Bang Theory’ star Johnny Galecki secretly marries Morgan, welcomes baby girl

He started this year off with a bang.

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

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

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

Morgan was pregnant at the time of the couple’s photoshoot, and gave birth to their daughter, Oona Evelena, “soon after.”

Included in the in-depth profile were stunning shots of Oona Evelena’s nursery, which included an animal-themed wallpaper, an expansive beige rug, a massive stuffed rabbit, an RH cabin bed and a leather tiled roof.

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

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

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

” [I] never felt like much of an Angeleno,” Galecki said, despite living in LA for 30 years. “And I did try.”

“I say that with sadness, not with snobbery,” he continued. “Thirty years is just a very long time to live in a city that you’re not all that comfortable in.”

Since “The Big Bang Theory” ended in 2019 after a whopping 12 seasons, Galecki has remained relatively out of the spotlight. In 2020, it was revealed that he and Meyer, 27, split after nearly two years of dating.

The “National Lampoon’s Christmas Vacation” star has remained tight-lipped about his romance with his marriage, too, minus 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 a sweet snap.

“#absolutehappiness Thank you to Mickey & gang for a magical post-holiday holiday,” Galecki wrote in the Instagram caption on Jan. 13.
