The Pretty Little Liars alum, 35, announced Friday on Instagram that she and her Suits star husband Patrick J. Adams welcomed their second baby together, daughter Elliot Rowena Adams, on Saturday, May 15. The pair are also parents to daughter Aurora, 2.

"Ms Elliot Rowena Adams joined us on May 15th under the wildest of circumstances. A whole new ERA for this family. Welcome, my love," Bellisario captioned a black-and-white photo of herself holding the newborn, a picture taken by "papa" Adams.

Bellisario and Adams tied the knot in December 2016.

For Mother's Day last month, the actor celebrated his wife, writing, "You are all places at once, doing more things than I can count, keeping us alive and teaching us to smile and laugh through all of it. I can't pretend to understand how you do everything you do and with such grace and kindness and humor. But I'll never stop being grateful for every single second of it."

The actress also meditated on becoming a mom, sharing a selfie of the top of her firstborn's head.

"To the magical creature that somehow decided I was the body to come through. You have given me the greatest gift on earth," she wrote. "I don't know what the hell I was doing before you. But I do know there were a lot less interesting selfies on my phone. Thank you for choosing me to be your mama."
