'The Big Bang Theory' star Johnny Galecki "over the moon" to be expecting baby boy

Earlier in May, Big Bang Theory star Johnny Galecki and his girlfriend Alaina Meyer revealed they had a little one on the way.

The couple announced the big news together on Instagram on May 3, claiming there was "truly love out there for all."

They wrote: "We are absolutely over the moon to announce that we will soon be welcoming a little one into this crazy and wonderful world. We ask that you please respect our privacy during this celebratory time for us and our families. There truly is love out there for all. We hope ours is the ember of yours, as we feel yours is the ember of ours."

While you're here, why not take a look behind the scenes of the final Big Bang Theory episode?

With the expectant parents ready and raring for their new baby, there was only one question left to answer: is it a boy, or a girl? Well, now we know. Just this weekend, the happy couple were thrilled to find that they're having a boy!

At a gender-reveal paint party, filled to the brim with blue and pink treats, the actor and model revealed they were having a son.

Surrounded by their loved ones, the pair made their joy known on social media, with Johnny writing: "A day I’ll never forget. ❤️❤️❤️ @alainamariemeyer".

His 22-year-old girlfriend Alaina added: "I can not wait to raise a baby boy with my love. He will follow in his fathers [sic] footsteps of being a generous, loving, chivalrous fellow 💙".

During an appearance on The Talk earlier in the month, the Big Bang star - who had his nails painted pink - had admitted he was hoping for a girl, saying: "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.

'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."

Judging from Johnny's overjoyed online reaction, he doesn't mind having a baby boy in the slightest! Congratulations to the happy couple!
