Emily Deschanel gave birth to a boy! Huzzah! Emily and husband David Hornsby welcomed their first child, a boy they named Henry, on Wednesday. Emily announced her pregnancy last Spring, and it was written into Bones so the “Dr. Brennan” character is pregnant too, although God knows what they’re going to do for this new season (starting in November). Previously, Emily spoke about her pregnancy diet – she stayed vegan throughout her pregnancy – and her birth plans for a doula and a hypnobirth.

And baby makes three!

Bones star Emily Deschanel and her husband, It’s Always Sunny in Philadelphia’s David Hornsby, welcomed their first child Wednesday, a baby boy named Henry Hornsby, Deschanel’s rep confirms to PEOPLE exclusively.

Deschanel, 34, and Hornsby were married in 2010. The actress maintained a vegan diet throughout her pregnancy.

The new mom’s Bones co-star TJ Thyne took to Twitter to share the happy news. “CONGRATULATIONS EMILY D!!!!!!!!!!!!!!” he Tweeted Wednesday. “Yay yay yay!!! :o)”

But he’s surely not the only one celebrating Henry’s arrival.

In April, shortly after her sister Emily announced her pregnancy, Zooey Deschanel could hardly contain her excitement, Tweeting: “I am super excited to be an aunt!”

Congrats to Emily, David and little Henry. I like the name Henry Hornsby. It sounds like a professor’s name, right? Like, “Oh, Dr. Henry Hornsby, professor of Classics at Harvard? His office is in that building.” I hope they don’t end up calling him “Hank”.

Seriously, though – what’s going to happen with Bones? After Temperance got knocked up like two seconds after bonin’ Booth, what’s in store for the new season? I’m concerned.
