Camilla Luddington has officially joined the club of Greys Anatomy stars who have children. (Its a very specific club, OK?)

The actress who has played Jo Wilson on the last five seasons of the show gave birth to her first child, a baby girl.

Luddington announced the news on Tuesday with a sweet Instagram video of herself, her new daughter and her daughters father, actor Matt Alan.

Luddington also revealed her babys name in the post which is drumroll please HAYDEN!

She wrote in the caption,

We have a new great love in our lives our sweet baby girlHayden

Isnt that just the perfect name?

Jo Wilson fans might have been hoping for a Greys Anatomy name like Josephine or Meredith, but oh well.

But I do have a fun little bit of trivia for diehardShondaland residents: There actuallyis a Hayden in Greys Anatomy. Sort of.

In Season 9, Episode 21, Sleeping Monster, Cristina Yang is reading a book called Haydens Progress.

A little bit of googlingtells me that no such book actually exists. So what is this mysterious, fake book that the set department came up with for the show?

Could it possibly have something to do withCamilla Luddington, who had just joined the show as Jo that season?

I mean, no, probably not. Its almost definitely a coincidence. But still, its fun to speculate.

Luddington and Alanannounced theirpregnancy back in October. Though they are dating, the coupleare not married.

Alan is also an actor, and recently appeared as Seth in three episodes of the Netflix original series, 13 Reasons Why.

Luddington got a little present from the Greys Anatomy team in light of her baby news, which she also posted about on Instagram, writing in the caption, When the #greysanatomy wardrobe Dept give you a baby gift.

The baby onesie reads,

I know Jos real name, but I dont know how to talk yet.

So I guess the real question is, which Shondaland resident knows how to speak baby?
