Big Bang Theory actor Simon Helberg and wife Jocelyn welcomed their first child together last week. So what’s the little one’s name?

Well, we have a theory about why Simon Helberg might be smiling more often than usual…

The Big Bang Theory star and his wife, Jocelyn Towne, welcomed a baby girl last Tuesday.

And they named thee… Adeline!

"The family is thrilled," a source told Us Weekly. "Simon is excited to be a father. He's been doing his reading."

This is the couple’s first child; they’ve been married since 2007.

Aw, Adeline is actually an adorable name. Can we all please add it to our “Best 2012 Girl Names”? It’s exciting to see a little celebrity baby not named after a continent, country or a fruit. Yay!

There ye have it. Babies one mo’ time.
