She followed up with a cute photo of her new bracelet, adorned with the "H" initial for baby Hayden. What a sweet little family! Keep scrolling to learn more about her baby!

Is Camilla Luddington married?

No, the Grey's star is not married. She had her daughter with her boyfriend and fellow actor, Matthew. In fact, fans of the medical drama might notice her beau because he had a guest star role on the show. He played an abusive husband (and father) who her character, Jo, fought against. Thankfully, we're sure he's much different than that in real-life.

Was Camilla Luddington pregnant on Grey's Anatomy?

Camilla was actually pregnant while filming Season 13 of Grey's, however, her character was not. That meant that she had to hide her baby bump in order to preserve the integrity of her storyline on the show. She even hid the pregnancy from fans for months. When she finally announced she was expecting her first baby with Matt on Instagram she wrote, "Nods of respect to the few of you who guessed right in the past few months — yes I saw your comments on that Ellen/me video."

She later revealed the challenges of pretending not to be pregnant while filming. “My character on the show, as of right now, is not pregnant, so I have to make sure I don’t rub my belly on camera," she explained to Fit Pregnancy and Baby. "When I start rubbing, which I do mindlessly, the director points to her belly, and I know to stop."

How was her pregnancy?

Prior to giving birth, Camilla told a funny story about one of her pregnancy cravings to Fit Pregnancy and Baby. "I asked my boyfriend to pick up some Philadelphia Cream Cheese, which is pasteurized, on his way home," she explained. "Well, he walks in with some other brand, and I had a huge meltdown. I was raging because I didn’t see ‘pasteurized’ on the label. Matt had to run to the store again. It was all so ridiculous," she added. Too funny! Looks like she had regular cravings like most moms.

She is clearly so excited to be raising her little girl. "I want her to grow up knowing how strong women are. To be a little warrior who is not afraid to use her voice and stand up for what she believes is right. To navigate through life with courage and kindness, and to be one of the girls who says ‘you CAN sit with us,'" the new mother wrote on Instagram at the time.
